I'd consider making a move for murphy- if we could swap KT. Murphy averages a double double, and even though he may be overpriced, I'd take his overpriced contract over KT's. He has better range, better numbers 14/10 vs 9/7.5), and to my understanding, a better attitude. Plus, he's not 6'7".
I'd do KT + Hart for Murphy. Maybe even exchange Garcia for Hart, considering we have salmons/martin/artest (and whereever Douby fits in) at the 2-3.
Murphy has a pretty hefty contract- more than KTs, but I think I'd pay a bit more for him considering what he brings and the fact that he's 3 years younger. At the very least, hes an asset and probably one that is more valued around the league than KT.
I guess I just really want to see KT go!
