Ryan Williams as, IIRC, back by OTAs, as well. Remember ZOOM?
I think that Cooper will come back from the injury better than Williams did, but that's not to say that we can just assume that Cooper is going to walk in March 1, 2014 as a Pro Bowl-caliber lineman. He's never had to deal with an injury like this before, and he won't have played real football in more than a year. Maybe he comes in and watches film and works with his linemates or whatever; maybe he doesn't.
But it's not assumed that Jonathan Cooper is going to come back as good or better than he left.
