I mean you can say that about lots of games.
We say we beat ourselves because we are ND fans.
Clemson fans sure as sh!t aren't saying ND beat themselves.
Clemson caused the CJ fumble
Clemson caused the Procise fumble
Clemson caused the Chris Brown fumble
Maybe Kizer's bad read on his throw that got picked off was his fault more than Clemson beating us. But the guy still had to intercept it.
Those turnovers cost us the game and for sure Clemson caused three of them.
Corey dropped 2-point conversion. Corey dropped TD pass. Fuller dropped passes. But even with those, the turnovers are what cost us more than anything. And three of them were caused by Clemson.
