Shumpert has been getting the cold shoulder from the Knicks after enjoying a solid season last year. With the Lakers short on point guards and Kobe Bryant playing with the ball in his hands a little more, the Lakers are looking to Shumpert to help hold the fort until Jordan Farmar, Steve Blake, or Steve Nash comes back.
The Denver Nuggets and Tornto raptors have also been discussed as possible trade partners for Shumpert.
As far as Chandler goes, the Knicks say they aren't willing to move him but anything is possible, especially of they find a sweetheart of a deal. Why the Lakers would want to take on Chandler's contract and his health concerns are beyond me, unless they would take on Gasol.
