Patrick Kane has the luxury of having a full NMC. This means he can choose his next destination unilaterally. It looks like he will be exerting this power now, as he will likely get his wish of heading to the New York Rangers.
With reports that Patrick Kane and Blackhawks management are having issues, and that Kane is looking to make this transaction difficult, it sounds as if he will force his way into a Rangers sweater.
Essentially, if the Rangers have any interest in making the move happen, which logically they would, they can get Patrick Kane.
We will have to wait and see if anything comes of this, but as long as Kane stays strong with his wish, it could very well come true.
