Brannen recruited these guys. If he didn’t think he could get them to play good enough D he wouldn’t have offered. Effort won’t be a problem. There are also some techniques that can be addressed fairly easily.. Gabe will be fine
In the long run, yes. But I am talking about as a freshman. We've seen plenty of freshmen get limited minutes because of defensive mistakes: Harvey and Davenport just last year, Keith Williams sat behind Moore as a freshman.
Brannen has talked about how bench guys get less slack from him in terms of making mistakes. It takes time to learn to play defense and give effort on every play when you aren't used to it. I like Gabe's potential, but I don't expect much from him as a freshman.
