I think that Jerebko is a better fit than KO. He can actually play two positions, if undersized for Center. He is perfect off the bench. I think Danny should try to trade KO to move up in the draft. I also think that Smart, IT, AB, Young, Crowder, Sully, Jerebko, and Zeller should be the main guys that start next year.
I said earlier that I would love WCS in the draft, but I would be ok with drafting another center with defensive potential, and an offensive game that meshes with the offense that CBS is using (Passing ability and finishing at the rim when open or the best option).
But give Sully another chance to get in better shape, give Young a chance to improve his game this summer, and get a center who can play defense without being a liability on offense. See what we have next year with that. I think it could be a 4 seed in the playoffs in the east.
Next offseason after that, see what needs tweaking/overhauled and move from there.
