I don't like it. I wouldn't give up the 2018 pick. I think the Knicks are going to suck next year and that pick is going to be this franchises salvation.
I agree with using Amare, Bargs and Chandler as expiring contract deals as we saw Granger got the Sixers Turner. So yes use them to get the PG that is needed. Sign Cole Aldridge, get Fab Melo and Whiteside to replace Chandler. Create a center by committee plan.
I don't think Melo is coming back so next year to me is all about getting the top pick in the draft. I don't want wins next year I want an full blast tank job. Get a top three pick and build around him. With Amare, Bargs and Chandler all coming off the books. You have enough space to get two quality FA to build around the top pick all starting in 2015.
