I think butler and lee are here already, cheaper and help make curry/frye better. (an in shape JJ as well), we have a good wing defender if QRich is in better shape and QWoods continues to improve (he's pretty good already). The point is that the roster is already balanced.
And getting rid of Mo, Jalen and Francis will still keep it balanced if we bring in nobody to replace them.
Don't jump on the LB "I hate these knicks" bandwagon, Lee and Butler are more than preferred over Ratliff and Reggie Evans. And Ratliff had the same stats as Jerome James (when he was in shape) so we know JJ is the same (if he is in shape), so shoot, we have Lee, butler and JJ.
We have our roster, stop LarryLoving every other teams players.

I can honestly say, no kool aid involved, that I would rather have Lee and Butler get the minutes on the cheap and rebuilding path than theo ratliff and reggie evans. Lee, if given evans minutes is a better defender and rebounder and we've seen what jackie can do.
David Lee 5/5 in 14 minutes a game...Reggie Evans 5/10 in 24 minutes a game. In terms of shot blocking, JJ cost $5 mill, ratliff costs $15...do the math.
So, look at the roster, we have your wing defender in QRich (in shape) and you have the shot blocker in JJ and you have the rebounding and downlow presence in Lee and Butler.
You want to rebuild but at the same time you want to bring in high priced over hyped scrubs from other teams to take minutes away from Jackie/Lee and our other youngins.
We have our team...just open your eyes.
all kool aid all the time.
