Some pertinent numbers to munch on leading up to tonight’s Eagles-Redskins game:

The story on Wentz

-- Carson Wentz is 18th in the NFL in touchdown percentage (4.8 percent). He’s averaging a TD every 20.6 pass attempts. Last year, he averaged one every 13.3.

-- Wentz has thrown just four touchdown passes this season with “11’’ personnel (1RB, 1TE, 3WR). He’s averaging just one every 47.5 attempts with 11 personnel. Last year, he threw 18 with that personnel grouping (one every 16.8 attempts).

-- Just 33 of Wentz’s 78 third-down pass attempts (42.3) have produced first downs. That just the 14th-best percentage among quarterbacks with at least 50 third-down attempts. Last year, 50 percent of Wentz’s third-down passes (62 of 124) produced first downs.

-- Wentz has thrown just one TD pass on third downs of 8 yards or more. He had seven last year.

-- Wentz hasn’t thrown as many deep balls this season. Just 11.8 percent of his “aimed’’ passes (discounting batted passes and throwaways) have traveled 20 or more yards. Last year, that percentage was 15.5. His percentage of throws behind the line of scrimmage has increased substantially, from 12.2 percent last year to 18.1 percent this year.

-- The Eagles have scored a league-low 21 points in the first quarter this season. Wentz has a 71.2 passer rating in the first quarter. He has thrown just two touchdown passes and three interceptions. Last year, when the Eagles were third in the league in first-quarter scoring, he had a 118.3 passer rating, 10 TDs, and two interceptions.

-- The Eagles are 21st in red-zone touchdown production (55.3 percent) entering tonight’s game. Wentz has a 55.8 red-zone completion percentage and has thrown a TD pass every 3.3 attempts in the red zone. Last year, he had a 64.9 completion percentage in the red zone, and averaged a TD every 2.5 red-zone pass attempts. He wasn’t sacked a single time in the red zone last year. This year, he’s been sacked four times.

-- Wentz hasn’t thrown an interception in the red zone since Week 14 of his rookie season (2016). He has one red-zone turnover in the last two years, a lost fumble against Carolina in Week 7.

-- Wentz is averaging just 2.9 rushes per game. Last year, he averaged 4.9. He has nine rushing first downs, none in the last two games. He had eight in the previous five games.

Pass-defense problems

-- The Eagles are 20th in opponent passer rating (97.4), 19th in opponent completion percentage (66.1), and 18th in opponent yards per attempt (7.6).

-- In the last three games, opponents have completed 71.4 percent of their passes and averaged 8.4 yards per attempt against the Eagles.

-- The Eagles are tied for ninth in third-down defense (37.3 percent). But in the last five games, that success rate has jumped to 46.9. That’s the fourth-highest success rate in the league over that period.

-- Of the Eagles’ 28 sacks this season, just seven have come on third down. That’s the third fewest in the league.

-- The Eagles haven’t blitzed very often this season – just 17.9 percent, down from 21.7 percent last year – and they haven’t been very good at it when they have blitzed. Opponents have a 107.0 passer rating when the Eagles have blitzed. Last year, it was 69.3.

-- The Eagles have given up a touchdown catch to a running back in three straight games. They’ve given up just two to tight ends. But tight ends are averaging 12.6 yards per catch against them.

-- Michael Bennett has 4 ½ of the Eagles’ 12 sacks in the last five games.

The catchers

-- Carson Wentz and Nick Foles have thrown a combined 46 passes this season that have traveled 20 or more yards and have completed 17. Tight end Zach Ertz is 5-for-5 for 140 yards on 20-plus-yard throws and catches. Nelson Agholor and Alshon Jeffery have been targeted a combined 23 times on deep balls. They each have just three catches.

-- Agholor had 142 receiving yards on his three deep-ball receptions. He has just 325 yards on his other 37 catches. That’s just 8.6 yards per catch. Agholor, who had eight touchdown catches last season, has one so far this year.

-- Jeffery was targeted 39 times in the first four games after he returned from shoulder surgery. He had 25 catches for 306 yards, four TDs, 18 first downs, and seven third-down receptions in those four games. In the Eagles’ last four games, he has been targeted only 21 times and has 15 catches for 155 yards, no TDs, 12 first downs, and just four third-down catches.

-- Ertz entered Week 13 tied for third in the league in receptions with 84. He’s on pace to finish with 122, which would break Jason Witten’s single-season record for receptions by a tight end (110).

-- Ertz has an 82.8 catch rate in the Eagles’ last seven games. He has been targeted 64 times and has 53 catches.
