I was U in a freshman game a couple weeks ago so that a young R could get some experience. I was focusing on the blockers so hard that a pass whistled right by my ear as I made no move to avoid it. It was so close that I could hear a "whooshing" sound. Of course, I stand 6-3 so I am not your prototypical U. (in a lot of ways!) I like the U spot. Lots of action there. When I retire, I plan to become a U.
