I want to say he is impressive but its still to early, the knicks are in a great spot, we actually got a FA Center at fair value and S&T for chandler cleared up enough money to sign the equivalent of two separate 2.5 contracts.
There are rumors we're trying to take advantage of Atlanta's mistake (amazing that the knicks are the team taking advantage of another teams mistake) to get JC and maybe barea will come for basically nothing to win another ring. But lets be clear this is all thanks to donnie. How man GM's would have the courage to tank 2 years and trade dimes for pennies just to make a team a contender again.
Chandler basically ended the bidding for his services once he heard new yoek was interested because we had Amare, and Melo. Last year the knicks got the steal of the draft in fields and this year shumpert is look like another fine prospect. I do think the T-Mac deal wasn't the best but who knew miami was in the runninh like that. The original plan had been lebron & bosh/Amare. However, Amare and Melo has just as much potential.
So while I like what I see so far I wont be able to give a fair opinion until Grunwald has left and you can judge his moves in hindsight.
