I don't really see any realistic trades out there. That Rubio trade certainly doesn't make much sense for the Timberwolves. They'd be downgrading at point guard and the only thing they'd gain is an injured Metta World Peace, who's been disappointing this season anyway.
Yes, so there's a good chance they could keep Murry and Leslie in the D-League if they don't make the roster. With that said, that would be contingent on them agreeing to a D-League contract, because they might want to play elsewhere if they don't make the final 15.
I think they might give him a D-League contract, but based on recent rumors they're looking for a big man with the final roster spot. As good as he looked in summer league, the Knicks don't really need another point guard but they do need some more help behind Tyson Chandler.
