As a partial answer to your question, most of the speculation regarding the guard situation has frosh Tyler Ennis starting at the point. He is a highly skilled pg who has a complete game. Great passer, good mid range and outside game, and can take it to the rack. Love his game, not the athletic freak that MCW is, but has good size (6'3"), but has better overall skills. He actually has a jump shot.
Michael Gbinije is the redshirt from Duke. Another 6'6" guard. Hoping he will be an improvement over Triche. Another player with good overall skills and athleticism. Most see Cooney coming off the bench, which is a good thing.
Tyler Roberson, aka The Beast, is maybe the player I am most excited about. He is a 6'8" PF with good skills. He has an outside shot and can also put it on the floor. He is an excellent rebounder. I am hoping for a more offensively skilled version of Jerami Grant. I think Roberson will be the first forward off the bench, with CJ and Grant starting.
Chinonso Obokoh is a 6'10" center from Rochester. He is more of a project and is insurance if something happens with the center position. Likely redshirt candidate. Very athletic. Has a face up jumper and plays hard. Not very polished on the offensive end. I think in the long run will be a better version of Keita, but don't expect much for a couple seasons.
Ron Patterson, 6'5" guard was a commit last year to Indiana. Enjoyed a successful season up in New England prep league. Didn't have gaudy numbers because of the players on his team but I believe was the player of the year in his conference. Has a nice outside shot, can take it to the basket, and is a very good defender. Having an extra year to develop may help in what he can contribute next year.
Finally BJ Johnson, a swing 6'7" swing forward out of Phillie. His father is a frequent poster. Seems like a great kid with a good work ethic but I believe is young for his grade and has not physically developed. Another kid with great skills and potential down the road to be a big contributor.
