After buying the Cavaliers in January, new owner Dan Gilbert fit right into the ranks of fickle pro-sports owners. Before he had time to redecorate his new office, Gilbert started firing people like a smaller, less combed-over version of the Donald. Head Coach Paul Silas - You're fired! GM Jim Paxson - Pack your bags! Even the guys serving peanuts started looking over their shoulders. Gilbert also initiated some much-needed improvements at the Gund, beefing up arena security and vowing to improve in-game entertainment, with help, of course, from part-owner Usher. He also ordered a new, over-the-top scoreboard that does everything but set picks. Hopefully, with all Gilbert's changes, it will rack up some points too.
