There's every snap vs. Missouri. I simply just can't find the plays you are talking about here. The only one close is where he blocked down on the QB strip play where the guard was supposed to get Ealy. Look again, that's not Robinson being run around. It's #62 Guard Chris Slade.
As far as the point regarding Robinson needing work in pass protection (Pace did too, btw). No one has said otherwise about his his lack of experience there. All I stated was that he looks like he has the feet to do it.
As far as 2012, the former high school guard was playing LT for the first time. He couldn't have improved during his redshirt sophomore season? Obviously, the NFL personnel people believe so. And how much of the issues were on Robinson anyway? For example, the Browns gave up 49 sacks last year (3rd worst in the NFL) with Joe Thomas at LT and Alex Mack at center.
