I don't know shinola about the players who haven't suited up for us yet, except for the well-informed gossip on this board. And if that's all I have to go on, and assuming we have 3 sit-out transfers, I think I'm going to agree with what @khoock just said above about Arop, Mayen and Andre having the least chance of starting (or being in the rotation, frankly.)
So, starters ...
Banton (too much smoke around his name to doubt there's fire there)
Webster (someone has to be your primary ball handler and with Mack gone ...)
Allen (he got his 4th star for good reason: the kid is a baller who can score at 3 levels)
Thor (there might be a lock down in Iceland, but Thor can find a basketball hoop and launch 1,000 treys a day if he wants; he'll be ready)
Walker (I'm going with Derrick over Yvan because of athleticism and rumors about his developing offensive game)
That's just a wild-ass guess.
After that, I've got:
Shamiel (is our 6th man)
Yvan (gives us good rebounding presence in a reserve role)
Wait, there aren't a lot of guards to bring in off the bench if we don't get at least Kobe King cleared. So ... Lat Mayen because he can hit threes?
Having said all of this, probably Lat Mayen comes in, takes the world by storm, has us all saying "who the hell is this guy and how did he fall into our laps?" and gives us 13 and 8. OK, probably not, but ya never know.
