24-year old shooting guard O.J. Mayo is a flat out better basketball player than Tony Allen is and he should be starting.  Mayo has played in 18 games (0 starts) for the Grizzlies so far this year and he is averaging 25.1 minutes, 11.9 points, 3.2 rebounds and 1.7 assists per game.  Mayo is also shooting 42.2% from three point range (27 of 64), as he is bringing big time firepower off the bench.  They have tried to trade him a few times, but they would be better off just playing him more as he is a darn good basketball player.
