Business as usual. Fans willing to trade a guy they don't like for someone they do like. And always wanting to trade only expendable guys. Too bad the other teams are not in on it just to help the Celtics.
Right now, Bass is okay but as said, if you want to trade him for a bigger player, then expect to get a worser bigger player. Someone like a Ryan Hollins for example. Size is at a premium and if you trade smaller for bigger, you should expect less talented as well.
In terms of Terry, Melo (and others mentioned), really difficult to tell if they have much of any value at all right now.
