I guess I'm a little worried about Center. But I always worry when a productive senior leaves, and many times the next guy just steps up. The Trudo depth chart thing is a little off to me as well, but maybe it's much to do about nothing.
From the WR standpoint, it's Estime that I think sticks out the most as an impact guy. And outside of that, I just think there are enough bodies with experience for it to be an improved position.
It's probably a good thing that we don't have a unanimous worry on offense.
