We'll there's always the NBDL. We'll probably send all three of them down to the valley at one point or another. That team would dominate the developmental league, lol. I don't see a problem with competition. If they're good enough, they'll break the rotation. If they're not, they'll get a chance when someone gets injured.
Mike ought to try to make as much money as he can before his bball window closes for good. He could wind up like Ray Williams, a pretty respectable ball player that had a fairly long career but only made 2M his whole career. He is sleeping in his car and fishing off a pier for his paydays now. http://nba.fanhouse.com/2010/10/11/the-nomadic-life-of-former-knicks-captain-ray-williams/
Mike Harris is not the kind of player we can't replace, no more than Von Wafer was. Ish might be special. As far as packaging some of these players in 2-for-1 deals, well yeah - that's the plan. Just waiting for the deals to come along.
