The 2005, 2006, and 2007 coaches of the year have all been fired since the beginning of this summer. I wouldn't be surprised if Mr. 2008 is on his way out, too.
Mitchell was and is a horrible coach. HORRIBLE. Frank owned him two years ago in the playoffs, owned him in the last game. His game decisions are dreadful, particularly in the clutch. How the guy lasted this long is beyond me.
