I get that, but I do think that we could easily replace their production with rookie-scale or vet-min contracts. Maybe not Aminu, but certainly Ed. The only good thing about either player is their contract - and I don't want to hold onto minimally skilled players just because they have decent contracts.
As much as I hate Aminu's game, if we only trade one of the two I'd rather trade Ed. But if we keep Aminu for next season he can't be allowed to play during the final 6 minutes of the 4th quarter - he should be limited to about 18m off the bench.
