I expect Karaban, Diarra, Ball, Johnson, Stewart all will be around next year. That's a pretty awesome 5 to build on. Ross too. He was a little too buried on the bench even early in the season and definitely late, but he has talent. Add in Nowell and Abraham (loved what I saw from him in the championship game) and you've got a solid 8.
Stewart needs to be more reliable from 3, but TBH I love the look of Ball's shot. I always see it online and expect it to drop. Roumoglou has a chance to be a sniper off the bench, and he's got great length and basketball instincts - needs strength. Singare has 6 months of work to put in on strength training, footwork, defensive post play, and he can be a major contributor. He's athletic and could take a big step up working in the program.
I think we need a high level portal center, another sniper of a shooting guard and McNeeley. There's your team for next year. Final Four, here we come again.
