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.
