A lot of Bryce's issues this season stemmed from his injuries. The light was starting to come on for him towards the end of the season after he came back the second time and probably would've turned on sooner had he not been injured. I'd be very surprised if Thompson wasn't the starting 2 next season.
Having Coach Ramsey actually be able to do an off-season program with these guys is going to be huge. Harris adding strength this off-season probably won't be an issue barring an injury and in the fall he and Yesufu should have a really nice battle for the starting PG spot. There's no reason Harris, Thompson, and Yesufu shouldn't play basically all of the 80 available minutes at the 1 and 2 spots next season.
Part of what Scott Drew has done is redshirt everyone possible and with the depth KU has, there's really not a reason not to redshirt Pettiford next season unless he comes in and is clearly the best option at the PG spot which I don't think he will be. This is what makes a lot of Baylor's players good defenders is spending a season guarding players better than themselves.
Here's what I'm seeing as the rotation next season.
Harris/Yesufu at the point and redshirt Pettiford. Jossell if he's still here gets spot minutes mostly in end game blowouts.
Thompson/Yesufu at the 2 since Yesufu can play off the ball.
Agbaji/Braun at the 3 spot. If Braun gets his 3 ball back, then you can work him at the 2 some as well.
Wilson/Clemence at the 4 spot and I'd personally redshirt KJ.
McCormack/Martin at the 5 spot. With Martin's outside shooting, I could also see him playing some 4 and getting a little high-low going with Dave as well. Mitch would likely get some minutes when Self needs a little more quickness at the 5 spot. I'd redshirt Curry so he can focus on slimming down some.
