IMHO, the biggest unknown is the WR/TE group, not a real shock here. We could have 2 rookie TE's and 2/3 rookie WR, I assume at least 2 Weill make the roster. Not thrilled with Britt and Quick both being the top 3. As already posted, just don't think Quick has earned the privilege to be on the roster!
My biggest worry with the Oline isn't talent, but injuries. We could have 2 2nd year players and a still developing LT. I think the talent it is there, if they can stay injury free, i.e. None of the starters last for the season... I think they can be pretty solid.
