Kolb beat Atlanta this year and looked good doing it. Andy Reid is really good at coaching up QBs. So I wouldn't rule Kolb out completely.
Delhomme, in the middle of one of the worst meltdowns in nfl history, looked good against the Falcons last season('09). When they had much of the same players on defense. Just saying. I think they're the reason why Fox kept starting Delhomme.
