I feel pretty good about the offense. I think the changes they made to camp and preseason this year, especially forgoing joint practices with other teams in favor of focusing on what they needed to do in practice and giving the starters more reps in preseason, are going to pay off this Sunday.
I feel good about teams as well.
The defense? That's the big question. We've heard the "oh, we weren't really trying, don't worry, it'll all be different when we hit the magic button ahead of week one" talk before, and pretty much every time it's not any different. So I expect that they will look awful Sunday and we are going to need to score 40 to have any hope of a win.
I do think the D will improve once they get a few weeks in the new system under their belts and all the position battles/question marks work themselves out. But the O is going to have to carry the load for the first month of the season.
