ARLINGTON, Tex. – Was the Eagles' 33-10 thrashing of the Cowboys on Thursday a statement? It's difficult to say for certain with a rematch only two weeks away. If the Eagles lose in Philly it won't mean as much, but the way they dominated in Dallas suggests they are a better all-around team. Here' what else we learned:

1. Mark Sanchez, when in rhythm, can run the offense like a point guard. The offense looked as sharp as has all season in the first half as Sanchez had the troops marching up and down the field. The Eagles totaled 292 yards, and if weren't for a few missed opportunities in the red zone, they could have posted 35 points by the break. Sanchez completed 20 of 29 passes for 217 yards and a touchdown. He has completed 69 percent of his passes over the last two weeks and has accurately distributed the ball on short-to-intermediate routes. "I think he's just getting more comfortable," Chip Kelly said. "I said it earlier in the week: he missed an entire year of football. There's no substitution for playing." Kelly has done a fine job tailoring the passing plays to Sanchez' strengths, moving him out of the pocket and having him throw on the run. He wasn't asked to make deeper throws in Dallas, but with the run game having so much success and play-action fooling the Cowboys, it wasn't necessary. Sanchez has often used the point guard analogy, dating back to his time with the Jets, but it's apt here because the Eagles offense has a fast break feel when it goes up-tempo. Sanchez is also quick with his release. He's averaging only 2.52 seconds in the pocket before throwing, which is the sixth fastest in the NFL. Nick Foles, who underwent a CT scan on his broken collarbone on Friday and seems to be healing at the expected rate, averaged 2.8 seconds. Sanchez also ran for 28 yards on seven carries, several on option plays, which added another element to the offense.

2. The offensive line had its best game of the season. With each week the unit appears closer to returning to its 2013 form. It just took some patience, and Kelly has displayed it. He knows his offense is lethal when the ground game is humming, and to the coach's credit he has hardly ever abandoned his commitment to the run. Center Jason Kelce and left guard Evan Mathis are one week further removed from their injuries. Right tackle Lane Johnson is playing at the level he finished at in his rookie season and reminding everyone why the Eagles drafted him fourth overall. Andrew Gardner has proven to be a more effective run blocker than Matt Tobin at right guard. And Jason Peters has been arguably the best left tackle in the game. The line opened an assortment of lanes inside and out and the Eagles rushed for a season-high 256 yards on 47 carries (5.7 avg.). "I think we finally started gelling," Kelce said. "We finally started to see the cohesion."

3. The Eagles were in better shape. The Cowboys looked slow in the first quarter. They looked gassed by the second. It is impossible to say for certain why that was. Perhaps the flight home from the late Sunday game in New Jersey affected them. Maybe they feasted on Thanksgiving dinner a day early. But the guess here is that the Eagles were better conditioned and better equipped to handle the short turnaround. Yeah, sports science. Kelly believes in it, as do his players. Maybe there isn't any scientific proof that the sports science program has benefitted the Eagles. But they have brought into it, and there appears to be, at the very least, a mental advantage. "I think our guys had a great approach starting Sunday," Kelly said. "There were a lot of guys in the NovaCare Sunday night while our coaches were starting to implement the game plan. There were a lot of guys running around the building doing rehab and recovery protocols. That kind of tells you about the mindset of his group." It could pay off further as the season winds its way down in December.

4. Speaking of which, the up-tempo offense should be even more of a weapon in December. Kelly hasn't always been pleased with the tempo of his offense. He said earlier this week that NFL officials just don't move as fast as the collegiate ones did when he was at Oregon. But he seems to want more out of his offense. He seeks perfection, after all. He seemed pleased with the Eagles' tempo in Dallas, particularly the pace on the first two drives as they opened a 14-0 lead. "We wanted to press the tempo on them fast and see it they could hang," Johnson said. "I think we ran the plays as fast as we could. We pushed the tempo and got 14 pretty quick. That made a statement early." Some of the Cowboys weren't willing to admit that the tempo got to them, but defensive end Jeremy Mincy suggested there was cause and effect. "It was fast," Mincy said. "You have to give them credit. They did a good job of game planning us. We were losing gaps which we usually don't do."

5. Fletcher Cox was arguably the best player on the field. The Eagles defensive end has been performing at a consistently high level all season, but Thursday was the first time he may have gotten the national attention he justly deserves. Cox helped clogged the middle with Cedric Thornton and Bennie Logan, but he also fought off blockers and made stops on run downs. His tackle for loss on a DeMarco Murray rush on second down and one at the Cowboys 9 was a huge play. He also had a sack after winning a one-on-one battle, and pushed the pocket into Tony Romo on other pass rushes. I wrote about the Eagles defense making a statement by holding Murray to his lowest rushing output of the season (20 carries for 73 yards) and Romo to his lowest passer rating (53.7) for my newspaper column.

6. LeSean McCoy never lost a step, he only lost his confidence. After averaging just 2.9 yards a carry in the first five games, McCoy is rushing at 5.0 yards a clip in the last seven and is now at 4.2 overall. He has eclipsed 100 yards in four of the last seven games. He is getting into a groove. What has been the difference? There have been a variety of factors, but mostly, it seems, McCoy is running with less hesitancy and more confidence as the line has improved its blocking. The line opened some mammoth holes in Dallas and McCoy shot through them and did his thing in space at the second level. He had a fumble in the third quarter, but bounced back a series later and scored from 38 yards out. "He's a big-time player," Kelly said. Last week before the Titans game, Kelly met with his running back for a pow-wow. He had noticed McCoy's public displays of frustration and reminded him that the only opinions that counted were the ones within the NovaCare Complex. "I just know he always has my back," McCoy said. He didn't say it after the game, but McCoy wanted to get the better of Murray.  "I know where I stand," he said after rushing for a season-high 159-yards on 25 carries.

7. The receiver group showed its versatility. It hasn't been especially noticeable, but the Eagles' receivers have increasingly been used in a variety of ways. Slot receiver Jordan Matthews had a few more snaps on the outside vs. Dallas. Josh Huff was lined up in the slot for three straight plays in the second quarter and was on the field for 22 of 77 snaps. Jeremy Maclin led the receivers with 61 snaps, followed by Riley Cooper (58) and Matthews (52). Brad Smith even had 16 plays. Kelly likes his wideouts to be interchangeable. He wants them to know each route concept on a play. He may not always shuffle the group, but it gives him flexibility. One other note: Huff had his first rushing attempt in the fourth quarter. It may mean nothing in the long run, but Kelly may want to convert the rookie into a receiver-running back hybrid. Huff has a tailback build and has obvious talents with he ball in his hands. He hasn't had as much success yet on downfield throws.

8. Sanchez isn't afraid to get in a teammate's face. Early in the fourth quarter, the Eagles had to burn a timeout near the goal line. Sanchez appeared to be upset with Cooper, got in his face and seemed to point to the spot where he thought the receiver should have lined up. "Listen to me!" Sanchez yelled. The conversation continued as they walked to the sideline until Brent Celek interceded. "We're a family," Sanchez said. "It gets heated and we can get upset. Both of us had something to say and we said it. I'd rather have something than someone who doesn't care. Neither of us took it any further." Cooper wasn't available in the locker room after the game. The quarterback and receiver haven't always been on the same page with certain passes this season. Sanchez threw to Cooper a play later, but Cooper wasn't looking and the ball hit him in the side. Cooper made headlines earlier this week when he jokingly said that his decreasing snaps had something to do with Maclin's contract situation. Maclin didn't see the humor and said "that was not a very smart thing for Coop to say."

9. Bill Davis' scheme was sound, but Romo obviously wasn't himself. The Eagles defense deserved props for winning the battle up front against a solid offensive line, keeping receiver Dez Bryant (four catches for 73 yards) in check and limiting the Cowboys' other weapons. But there was no way Romo was playing at full strength. The Cowboys generally always want to establish the run early, but they leaned far too much on Murray, especially early in the second half when they trailed, 23-7. The only explanation was that Romo's back was stiffer than normal. He hasn't practiced for Sunday games until Thursday since his back injury, but was forced to move up his schedule a few days this week. When Romo (18 of 29 for 199 yards) did drop to throw, he tossed a number of passes that were uncharacteristically off-target. Cornerback Cary Williams intercepted a wide throw and safety Nate Allen picked off a pass thrown up for grabs. Romo has had sloppy turnovers in the past, but he was obviously restricted. Three of four sacks he took occurred when he just flopped to the ground. The Eagles got pressure, but he normally would have tried to spin out with one of his patented moves. The point is that a rested Romo should be able to move better when the teams meet in two weeks.

10. And a few quick notes. Emmanuel Acho was active but didn't play because of a groin injury. Casey Matthews took all the "Mike" linebacker snaps. Kelly said a less-than-100-percent Acho would have been first off the bench had either Matthews or Mychal Kendricks been hurt, which certainly didn't reflect well upon Marcus Smith. "Acho was out, but, really, if we had an injury, we'd have to go to [Acho]," Kelly said. … The Eagles' red zone woes continued. They scored only one touchdown in five trips inside the 20. Getting there and leaving with at least three points is of more importance, but the offense left points on the board. "We left a ton of meat on the bone," Sanchez said. … Kicker Cody Parkey connected on all four field goal (31, 22, 26, 25) attempts. He's been on the injury report with a groin injury and it appears to have affected his kickoffs over the last several games. He had touchbacks on only 2 of 8 kickoffs vs. the Cowboys and has only six on his last 22 (27 percent) kickoffs.
