Your memory is already failing you, eh?
It actual looks like my memory is failing me. I went back and read his draft profiles from a few sites. Looks like a was remembering fan opinions more than those of professionals. To be fair, I trust those on this board more than the pros anyway. But I think I was still on ramstalk at the time so there's that...
There was talk that he didn't have super polished pass pro skills, but with his size, strength, and mobility it should be easy. And again, the potential for him to fail at OT was acknowledged in saying he would at worst be a HOF guard (again a fan take).
Matthews was more polished but considered to have a lower ceiling. What I recall is that he was already maxed out physically and technique wise. He would be good but never a difference maker. But that's going off memory, which we've already determined is faulty.
