He was a difference maker as a run blocker even though he had average, at best, technique. He could have been an absolute nightmare on the edge if he had another year with HH.
I've always wondered how he would have done playing tackle, assuming he could have put on another 25lbs or so. He had the height, relatively long arms, and the athleticism/hips/knee bend to be an elite pass blocker. Hindsight is always 20/20.
He was definitely a unique athlete - started a few games at LB as a freshman, if I'm not mistaken, switched to TE as a sophomore, and had the frame to be an elite OT.
