I'm definitely concerned. We started out looking great with a hard to stop passing attack and a QB on track for MVP consideration. We look a bit lost lately, the game plans are lacking (IMO) and we can't seem to dominate weak opponents.
However we have a good record and we lead the division so we should be happy about that, at least in terms of we can get better while still being in a great position. We have a 3rd year QB that shouldn't be expected to have everything figured out yet, he's not a phenom. He figures things out through working hard.
I believe he'll get there and it may not necessarily be this year. The future looks bright with Allen.
