This game wasn't a fluke. Sure Clemson had a couple key turnovers, but those were more great plays by JOK than mistakes by them. ND had more total yards, more yards per play, controlled the clock, etc. If it wasn't for ND's 3 unforced errors in the redzone (Mayer's false start and drop and Book's fumble), this game would never have gotten to overtime and ND likely wins by at least 2 scores.
Also, Clemson's freshman QB is an amazing talent. ND wins this game even if Lawrence plays IMO, as QB play wasn't their issue. It was that ND was better in the trenches.
We'll see when they play again in the ACC championship, but at this point no ND fan should be afraid of Clemson (or anyone else for that matter).
