The Grizzlies need more out of back-up point guard Jamaal Tinsley. He has played in 34 games (1 start) for the Grizzlies this season and he is averaging 16.0 minutes, 3.6 points, 1.8 rebounds and 3.0 assists per game. Tinsley is only shooting 37.3% from the floor and 19.4% from three point range this season and that is just not good enough. The Grizzlies took a big chance in bringing in Tinsley and it has not paid off as of yet.
