Sam Mitchell has officially come off the Raptors' books and has signed on as an assistant under Avery Johnson to coach the New Jersey Nets.  There is no word about the specific responsibilities that Mitchell will inherit under Johnson, but chances are, Mitchell will end up being the "cool head" on Avery Johnson's staff.   He joins former Raptor Popeye Jones in rounding out Avery Johnson's staff. 

This may very well be the most vocal group of coaches in the entire league.
