You must be blind, wist. He blew up a critical 3rd and 1 play all by himself, and LSU had a blocker assigned to him. Biegel was fast enough to beat the blocker to the spot.
I don't think this kid in any way is our knight in shining armor at LB, but he's not a bad value in round 4. I do agree that Thompson needs to alter his approach to this position...it hasn't gotten him anywhere in 15 years.
