The only reason any of the young guys are "touchable," is that we have minimal time left with KG and PP. Otherwise, trading Bradley, Rondo or Sullinger is madness.(youth, improvement, great contracts, mad dog desire, etc) Id add Melo, Lee, Green, and perhaps even Bass to that list which I know NO ONE will agree with, and we would obviously covet all future draft picks.
But we do have PP and KG and we have maybe a 2 year window. (This window thing is extended so far to be ridiculous but who knew KG was eternal?) And because of that window, AND how much worse we still are without KG on the court, the future is still now. So almost everyone is up for grabs. Having said that, I feel the only players who should be untradeable are PP, KG, Bradley, and Sullinger. Rondo is nearly untradeable but Id still take Paul for him, or some other otherworldy package.
I don't know Bradley's upside. Frankly, I think its higher than Joe Dumars. Its Joe Dumars as the greatest on ball defender in NBA history. Thats the upside. a 6'2" Jordan on D, and Dumars on offense or better
Not trading that.
Sullinger is a bigger Paul Silas with a nastier attitude. I don't know what to compare him to more recently. A relatively earth bound guy who is probably actually almost 6'10' and has really long arms and very wide and positions himself perfectly at all times? A smaller Kevin Love? In any case, no way I let him go either.
Rondo? Rondo has barely played with the other young guys. Its absurdly short sighted not give him run with Sully, Bradley, and perhaps Lee, and Green and Melo
Bass isn't old either. We have a good young core and we best be really careful if we are going to shake that up.
GO CELTICS!
