Yeah, he's probably their best defensive player, if not their best player overall. He was a kid that originally committed to Michigan, and then was processed out late by Harbaugh, hence he landed at Pitt. It's a very, very big loss for them. They have literally no talent behind him.
Sucks for the kid, that's for sure. First you get dumped by Michigan and end up at Pitt, and then when it's your turn to shine you get a ripped ACL. Dude has had some bad luck.
It gives the Pitt stooges a good excuse that they will use when they go 3-8, though.
