Next year will be tough, I think no matter who is the coach, the portal will be hit hard. You are losing probably Jordan Brown and definitely Greg Williams, Terrance Lewis, Jalen Dalcourt. That is 3 starters and one of your off the bench guys.
Hopefully Kobe improves health wise and Joe Charles will take some of those minutes as he continues to get better and better, but it is hard to replace those 4 guys from the roster we have right now.
I assume that Marlin (if he is the coach next year, and based on this year I see no reason why he would not be) will be in the portal hard during the offseason.
