There certainly are A LOT of players I hope we bring back next season. Some because they're starting to develop, some because they're already awesome, and some because - even though they haven't shown anything - they are cheap so there's no value in getting rid of them. These are the guys I really hope we keep:
Awesome Keepers
Dame
CJ
Plumlee*
Developing w/ Promise
Harkless
Meyers (I know, this is the contentious one)
Cheap
Pat
Montero
Most everyone else I'm fine keeping, but also fine trading or letting walk if we can find a better replacement.
*Depending on what happens with the front court I can see selling high on Plumlee. For instance, if we could get Boogie for Plumlee and Aminu - DO IT. Basically I think we need a new starting PF or C. Vonleh would be fine if we got Boogie. Plumlee would be great if we got Ibaka/Millsap. But we can't start Aminu/Vonleh/Plumlee again...even Harkless/Vonleh/Plumlee or Harkless/Aminu/Plumlee needs to be something that ends this season.
