Id like to see the Knicks make a legit run now. I believe Shumpert has a great career ahead of him if he gets past his knee injury and commits to working on his game. I don't have enough faith in Shumpert's recovery and development to pass on who is still one of the best PGs in the league, still playing at a high level, and who is one of a handful of players in this league who could get Stat, Melo, and Tyson (not to mention the rest of the team) on the same page.
We know what kind of player Nash is right now and what he brings to the table. Shump has to get over a serious knee injury and develop his game. I would rather we get a player who can get everyone else to play at a high level, who has a track record of being able to do this, than pass on a deal over a player who we still aren't sure has completely recovered from a knee injury and who still has parts of his game that still needs work. For what? Some non existent contender in the future? The future is now with this squad.
We aren't going to be able to get someone who could have a dramatic effect on this team's fortunes like Nash by offering TD as the centerpiece of any trade. It will cost us but I believe its well worth it.
