I've only seen rodney play live once, and he was visibly disinterested in the game. But he has all the physical tools to be a star once he puts on some weight and improves his shooting ability. And when he focuses, he's very good defensively.
If tubby wasn't totally against the idea of redshirting, I would say he is a great candidate for it. As it is, if he can't get eligible, it does give him another year to work on his skills, albeit without the same level of coaching as he would get under tubby.
I can't wait to go nuts at the games after some of the spectacular plays that I'm sure he will make in maroon and gold, but I'm not sure he'll get even 5 minutes/game as a freshman. I will be shocked if he contributes more to the team than any of the other 3 incoming players.
However I also remember a post from a couple of months ago that was breaking down tubby's ball-line defense scheme and the thing that stood out is that it really relies on very athletic wings who can recover quickly to cover the weak side shooter, because that player is actually supposed to sag way off of their man down towards the paint to try to cut off passing lanes or double the post. Our defense did tend to give up a lot of those 3's where we didn't recover quickly enough, especially on a skip pass. Rodney is the perfect player to have at that position defensively, it's just the offensive side of the court where he really needs to work on his shooting before he'll be able to contribute.
I blame the coaching he got in high school more than anything, as they actually played him as more of a post player down in the paint, blocking shots, rebounding, etc. With a player of rodney's abilities, I think it's a crime not to at least put him in a position to work on the skills he needs to succeed at the next level
All in all, I think he's definitely a project, but by the time he leaves the program, I expect him to be a stud, and even if he never develops into a complete player, he will bring the fans out of their seats regularly.
