Back from the brink of divorce, Grizzlies guard O.J. Mayo insisted he's not bitter after an agreed-upon trade shipping him to Indiana failed to go through at the NBA's trade deadline. "We're still married and I'm happy to be here," Mayo said Friday following the Grizzlies' workout. "I think I belong here. It's my job to prove that I need to be here." Mayo wore a smile and his familiar No. 32 practice jersey as the Griz prepared for tonight's game against the Sacramento Kings. Griz coach Lionel Hollins said Mayo's role won't change and he'll be the first guard to play off the bench. Mayo was home watching ESPN and taking frantic phone calls from family, friends and teammates when the deal became public and then word came that the deadline had been missed. The Griz agreed to trade Mayo to Indiana for forward/center Josh McRoberts and a 2011 first-round draft pick. The transaction would have involved a third team but fell apart when New Orleans backed out at the last minute.
