Bledsoe is a good, not great player. Definitely makes some sense for the Knicks but the #13 pick does not do the Knicks all that much good. Anyone they get will not contribute at the level they will need for a few years if ever (assuming they want to put players around Melo and compete now).
Compare that package to Bradley and the Brooklyn 2016. That pick has more value and I think the Knicks would trade that one next year for another good player. Isn't that really close or better than the PHO package? Bradley would be good next to Melo.
I suspect that the Knicks are more interested in the player than the pick but I think the Celtics should be in play for this and they don't have to give up Bradley AND Sullinger plus #16 AND BKN-2016 to beat Bledsoe + #13.
