I think we can, but I don't think that means we will. Our defense is looking like they will be able to keep up in games, if not win it outright at times. Though facing Denver might be the only "hiccup". I don't think that Hill will lose us any games, but our offense is still has many question marks.
How bad is the offensive line? I think this is the biggest question, we can't run or pass effectively without an oline.
Can we rely on the run game like last year? As for most of the season we have been rather pass heavy, similar to the 1st 4 weeks of last season.
What is going on with Zac Stacy? I was really big on him going into the year and now he's on special teams.
Are the receivers getting open consistently or is the QB not getting it to them? I've seen receivers open a lot, especially on Ints but I can't imagine its all on Davis.
Is it play calling, defensive adjustment, or poor execution that dooms us in the 2nd half? 3rd and 4th quarter scores are keys to winning close games and we don't do it.
Imagine a healthy (indestructible) Sam Bradford with this offense? I generally try to avoid questions like this, but I'm still hopeful.
