Robinson is big enough - strong enough - and - agile enough. He went to O - line training camp in the off season and still had maybe his worst season as a pro. I think we have an individual that is incapable of intuitively performing the job that the Rams are asking him to do and I don't know if this aspect of his mentality is something that can improve over time. He basically just doesn't seem to know who to block - he doesn't seem to have a feel for the position or the ability to coordinate the physical and mental requirements needed to be an effective left tackle.
