Give Riley a break.  The man brought Shaq and Wade to Miami.  Did anyone really think he wouldn't come back to coaching?  The NBA is full of recycled coaches and whenever a team fires one, they just go to the pool of retired or former coaches.  Do the names Flip Saunders, Larry Brown, Doc Rivers, Nate McMillan, Byron Scott, Jim O'Brien, and others I could mention all have in common.  These are coaches that don't change jobs, just locations where they practice their craft.  Doc Rivers and Byron Scott are both good coaches in my opinion, but they beginning to become a part of that group like Don Nelson and Mike Dunleavy or the George Karls who move year after year to a new team.  Kudoos to the Mavs for giving some new blood a chance in Avery Johnson.  At least Riley stayed in Miami, but then again, he was in LA and NY.  It seems he likes the big cities.  That leaves Chicago to make a move for him sometime.  Who knows, i am willing to wager that Scott Skiles will be hopping on or off of the coaching  merry-go-round before the end of the year.  That will leave room for Stu unless he takes the Wizards job or some other team.  Once you are in, you are in for life.  The fraternity of NBA coaches is small, but you can always take your turn with Atlanta.  That is what I love about the NBA, they care about recycling!
