I'm a big fan of Porzinigis and I believe we at least should try and make some kind of a move for him, and I'm sure Ainge has already done that.
I think he is overrated and at the same time I think he is injury prone, but even taking those to things into account I believe he still might be the last piece in our proces of building a championship team, especially because of his contract.
The thing is, that we need a big man and New York need guards and wings who can play defence. It should be ideal, as the teams got what the other team needs, but I'm not sure we can make it happen!
