You apparently don't know much about how valuable a WR can block EXTREMELY well and at the same time be very surehanded.
I don't remember what game it was, but Reed was blocking a safety all day. I remember watching him and the dude was getting more and more pissed the whole game. Reed pissed the guy off so much by finishing his blocks, the guy lost it and hit him late and got a 15 yard penalty. Bills score.
That, my friend, is a tenacious and valuable WR.
