Update: Of course, now everybody's reporting that the Knicks might pursue Sessions. It'd take some heavy finagling for the reasons detailed below.
You, like me, have probably seen the Jose Calderon and Ramon Sessions trade rumors floating around and been like "Hey, wait, the Knicks desperately need point guard help. Gimme.". If you have had that experience, then you've probably also waddled over to the ESPN Trade Machine and been like "gimme gimme gimme click click click" (that's either the sound of you clicking a mouse or muttering in an African click language) only to find that New York's payroll situation is so bipolar that there isn't anybody even remotely equivalent in salary to those two players. Dan of The Knicks FanBlog describes the situation:
It doesn’t take a genius to notice that the Knicks have three contracts taking up the majority of their cap and then a bunch of filler. After the Broadway Bigs, the next highest contract belongs to Renaldo Balkman. And as good as he is, to nab someone like Sessions or Ridnour, I suspect the Knicks would have to sweeten the pot. And who is going to get ‘er done? Shumpert? Landry? Those combinations would work but would it be worth it for the Knicks to give up on long-term potential to fill a short-term need when 2012 free agency awaits with a litany of point guards?
Seriously, though, Carmelo Anthony, Amar'e Stoudemire, and Tyson Chandler each make double-digits of millions a year. Balkman, the fourth-highest paid Knick, makes less than $2 million a year. So, like Dan says, the only way the Knicks could deal for a point guard (or anybody) of that caliber would be to lump a bunch of smaller salaries together and just completely empty out the already scant depth they've got for a single guy. Seems unrealistic (yet familiar), though there are potentially cheaper, albeit less appealing point guards out there if Baron Davis takes too long to return or is deemed insufficient when healthy.
