Hard to say, because a couple of variables are unknown, namely:
- Does Coleman come back anywhere close to 100%?
- Does Bryant come here?
- Does McCullough come back anywhere close to 100?
- Does McCullough declare for the NBA?
- Does Gbinije declare for the NBA?
- Does Patterson stay or depart?
- Does BJ stay or depart?
Please note that I'm just listing the unknown factors, not advocating that any of the above can or will occur. For the purposes of responding to your note, I'm going to make a couple of quick assumptions:
- Bryant ends up at SU
- Coleman returns, but isn't 100%
- McCullough and Gbinije both return
- Patterson transfers
So, with that in mind, here's how I see the rotation:
PG--Joseph, backed up by Gbinije. Howard is the third option in a two-player rotation at lead guard
SG--Cooney, with Malachi Richardson backing him up and occasionally playing alongside him. Gbinije can also fill in here.
SF--Gbinije starts, but reprises his role as the team's primary lead guard / facilitator. Roberson can play here in a pinch. BJ returns and gives us a legit bench scoring option
PF--McCullough or Roberson start here. The other is a top bench guy. Diagne could fill in here, too. Lydon doesn't play much next year.
C--Bryant starts, Coleman backs him up. Both end up playing about 50% of the game. McCullough can also slide into the pivot, as can Diagne as the fourth option. Obokoh doesn't play much next year.
If Bryant doesn't come here, then it all comes down to whether Coleman can start or not. If he can, he's the center. If he can't, then while it is less than ideal, I see McCullough potentially starting at the 5 with Roberson starting at the 4.
