This thread actually made me laugh a little bit.
So you're telling me we should repay McHale for 'giving,' us KG?
Then he should repay us for the pick that landed Kevin Love, and giving him Al Jefferson, and other players that definitely filled his bench and depth up. In the NBA there is no, "you help me, and I help you."
Granted we wouldn't do anything too dirty to really take advantage of someone, because its bad business, and people rarely deal with people like that.
But to say we owe McHale a favor in return for KG is absurd.
