For me, it's pressure on the QB, specifically, sacks. The Cards tallied 27 in '19, tied for 70th nationally. The national leader was Pitt, surprisingly, with 51 sacks. There was a time, not so long ago, Louisville could have made a case for being Pass Rusher U. Marcus Smith and Lorenzo Mauldin most recently, but Peanut, Dumervil, Dewayne White, and Michael Josiah before them. We had guys who could get after the QB. That's been missing for a few seasons now. I suppose Greenard could have been the guy had he not transferred. Perhaps incoming freshman Yaya Diaby will produce. I can hear Moth now: "Sack by Yaya!"
