This is my feel on it. This D has been put in worse positions and fared similarly [by the numbers]. Last year, the D was in good position time after time to just make one stop and win the game. And couldn't pull it off, gave up sustained long game killing drives... Miami, UT, UVA. This D doesn't seem to be giving up killer drives. It's different not stopping a team from their own 20; versus from your 25, because they got a TO.
Also, they seem to be getting much more* pressure on the QB which isn't easily quantified (*all relative 10x miniscule is still small). But I do think the increase in turnovers is a function of scheme, not a fluke. If we had ball hawks like D. J. White, the Austins or AJ back there this year, we'd be pulling in interceptions like nobody's business. Simmons alone could have had like 3 vs UNC if he had more of a nose for the ball. Our young guys will get better.
