I never got around to it but Pitt and defensive line coach Tom Sims parted ways earlier this month right after National Signing Day. KDKA's Richie Walsh had it first, I believe.
The Panthers' line was, I thought, pretty strong all year long. They were eighth nationally against the run and also eighth in sacks. If you ask most fans about the biggest problem areas of the team, defensive line would be pretty far down, I imagine. The timing, too, was a little interesting in that it came right after National Signing Day when players were already on board.
