Has any owner ever enjoyed a championship more? Considering the decade, cash and passion invested into his Mavericks, he deserved it. After Dallas' first pro basketball title, Mark Cuban took the Larry O'Brien trophy to the urinal, took a cheap shot at sorta partner/definitely enemy Ross Perot Jr. and got the last laugh on his critics. Whether it's keeping the faith in Dirk Nowitzki, sticking with Jason Kidd or shelling out the big bucks to sign Tyson Chandler, Cuban is nothing if not determined to put himself and his team in the best position to win. As if that's not enough, every week he jumps into ABC's Shark Tank. Impressive.
