Gray to change his number??

I was recently visiting the zag shop for their clearance sale and saw that all of the #32 jerseys were being cleared out.  I asked why #32 and not #15 because of bouldin's departure.  The guy at the store said gray was changing his number.  He didn't say to what, or why.  Anyone got the scoop.  Maybe he's trying to change his inner zen by switching up the number on his back.  Maybe it will lead to the consistancy we are all praying for.
