My problem with Benson is (and always has been) what appears to be a complete lack of vision periodically. On simple plays where the blocking scheme does it's job, the Defense doesn't react well, he' a bruiser. Powerful, leg churn, good balance. When things get hairy, or the hole that is supposed to be there, isn't (I'd say that's the case 50% of the time in the NFL), he just doesn't ever seem to have any spacial awareness, or plan, or decision making ability, or vision. He just plows (high) into the nearest 320+ lb lineman and goes down. He's just so incredibly inconsistent in his play. His pass protection is equally inconsistent. You'll see him pretty effectively handle small speed rush DE's 1 play, then the next 2 or 3 plays he completely mis-reads his assignment, and gets Rex smashed.
/shrug. I guess this is a guy that I just won't have. I'm not going to be terribly suprised by either extreme of the spectrum.
