Gentlemen, start your quarterback controversies.

Kevin Kolb has played his way back into a conversation that Eagles coach Andy Reid is clearly uncomfortable having. Just as Michael Vick played well when Kolb got hurt, Kolb now has played well while Vick was hurt. And after this one, after a 31-17 win over an Atlanta Falcons team that arrived at Lincoln Financial Field as one of the top teams in the NFC, well, it will take all of Reid's considerable experience to keep the Vick-Kolb conundrum from consuming his locker room in the same way that it is likely to consume the fan base.

Kolb was very good against the Falcons: 23 for 29 for 326 yards, 3 touchdowns and 1 interception. His quarterback rating was 133.6. He has gotten better with every game this season, and that is undeniable. Why Reid decided to throw away his off-season game plan and switch to Vick as his starter remains the story of the season. Whether or not he could possibly switch back to Kolb when Vick is recovered from his cracked rib cartilage -- perhaps as soon as next Sunday at Tennessee -- figures to be the subject of an intense debate in the coming hours and days.

As will this: when might wide receiver DeSean Jackson be back?

On the second play of the second quarter, Jackson was illegally jacked up by the Falcons' Dunta Robinson. Kolb, under pressure, floated a pass out to Jackson on the left side. He caught it, landed on one foot, and then was about to land his first definitive stride when Robinson hit him about chin-high with his helmet. (Robinson received a penalty for hitting Jackson while defenseless.)

Both players collapsed and remained on the field for several minutes before walking to their respective dressing rooms with assistance. Both were described as having head injuries. There was no specific mention of a concussion, but it is fair to wonder when that announcement might be coming.

This was the first game this year where Kolb and Jackson were able to connect as they did in Kolb's two starts last year. When he left the game, Jackson already had a 34-yard receiving touchdown and a 31-yard rushing touchdown. Now, though, it is hard to predict when he might be back.

As for the Eagles' defense, for the second week in a row, it has accomplished Job 1: preventing the opposing running game from dominating. Last week in San Francisco, it was Frank Gore. Against Atlanta, it was Michael Turner. He was the concern and he did not come close to being a major problem: 15 carries, 45 yards, no big deal.

And so, the Eagles are suddenly 4-2, which is about as good as it gets in the NFC in 2010.
