obviously we don't know exactly why the offense isn't looking sharp but let's look at what we do know:
1) Our secondary has been very good in camp thus far which will certainly make it hard to complete passes. Sounds like our LBs are even covering pretty well. (I think our secondary may end up being the best in the league this year, esp if Watkins makes the starting FS position and keeps playing like he has so far in camp.)
2) TO hasn't practiced in a few days, that's our #1 WR threat and he needs time to synch with our QBs
3) We knew the OL was going to have some changes, some new players, a guy coming off a serious injury, and take some time to gel
4) Our defense was mostly set as a unit and has a lot of players now in their second year who are dramatically improved
5) A vast majority of our draft picks last few years have been on defense so the weight of our talent right now is there
6) Our defense was pretty good last year
7) Our offense wasn't that good last year
8) its easier and quicker for a defense (less moving parts) to gel than an offense
Overall, I think the chips are stacked in favor of the defense at this point in the season plus we knew we had a long way to go on the offensive side of the ball. Not really surprising to hear that our offense wasn't having that much success against our defense, even with TO (and esp without him).
