In my opinion, with some speculation by seeing videos:
Remove from the list: Kitchell (5), RJ (4-5), Gant (4-5)
Koang (4 - can defend the 3)
Arop (3-4)
K Smith (3)
R Smith (3 or Renn-type 4)
Bell (unknown)
Burnett (3 or Renn-type 4)
As long as they are healthy, I'm expecting Gant, RJ and Kitchell to get most of the 4-5 minutes.
If any on the list are good enough to bump one of them, that will be an incredibily good thing for the team and we will have depth at the 4-5 that we have never had. Remember, a good 4 that is playing 5 is better than most of the 5's that we have had. Some of the young ones on here probably don't remember who our center was in the Green/Renn/Menser years.
Many of us were fans during many lean years when we had under-sized centers that couldn't post up or make a put-back. Remember Johnson from Pike. I don't know if he posted up, caught the ball, and scored one time in 4 years. I'm so excited!
