To me Defense is needed at two positions (PG and Center), plus one the foward need to be good and you fine with one average and one subpar, because you need to score too in my opinion. Don't get me wrong I'm happy if they all play defense. What I need is a creator to me that is the most important thing, that is why I'm so high on Russell. Melo ain't gonna do it, and lets not have a pipe dream he is going nowhere, and unless your giving dragic close to the max I don't see that playmaker in 2015, and the knicks don't have their pick in 2015 so no benefit of being bad, so might as well try and compete.
You see can't see why the sixers would want a big man. With Emblid and Noel, don't understand why they would be trading up they are fine where they are in my opinion they need guards.
