Fun note on this: Mike Mayock said this was more impressive than John Ross running a 4.22. He expected Godwin to be around a 4.55 or a 4.58, something like that. Even if you disagree with this (which, I think I do because holy crap a 4.22), Godwin absolutely made himself some money today.
The main reason I'm optimistic is that when he's been at his best, Saeed Blacknall is horrifying. Watch how he obliterated Desmond King in these highlights and Wisconsin (which had one of the 5-best secondaries in the sport) in the Big Ten title game.
The issue is consistency and rounding out his game. If he can do those things, he'd golden. If not, that's when the DeAndre Thompkins and Irvin Charles and Juwan Johnsons of the world become so much more important.
If ND ever has, like, three bad seasons in a row then people will start tuning them out. Of course you then run the risk of them going 9-3 one year and everyone writing "is Notre Dame back?" columns.
Terrence also has the added benefit of being taller, longer, and stronger than most point guards. Plus he seems like the kind of dude who takes pride in how he performs on that side of the ball. It's so fun.
