Mike Taylor - You should know who Taylor is but this point, as he's probably the D-League's biggest recent success story.  After making his name in the D-League primarily as a scorer and a dunker, Taylor finally got his shot with the Clippers last season, and he made the most of it.  He's still not a premier point guard, as he averaged just under five assists per 36 minutes last season, and he's not a great three-point shooter, but he filled in admirably when Baron Davis was out with injury, and he works hard and hustles.  In some ways he makes more sense on the Memphis bench than Allen Iverson does, and if Taylor can work to limit his turnovers he could be an interesting player for the Grizzlies' backcourt.

Thomas Gardner - Gardner initially got some notice as a solid perimeter shooter, but that skill has yet to translate in NBA games (his career eFG percentage is .364, and his three-point percentage is .200).  He's not particularly athletic or quick, and he doesn't offer much in the way of assists or rebounds, so Gardner will have to show that he can adjust to NBA defenses and still make his shots if he wants to show that he can stay in the league, let alone on the Grizzlies' roster.

Leon Rodgers - Rodgers has been a scoring big man over in China and around Europe for the past several years.  Last season with the Jilin Northeast Tigers he averaged 35 points on 56 percent shooting, including 42 percent on three-pointers.  He's an okay rebounder, but the biggest question with Rodgers is whether his prodigious scoring ability will translate over to the NBA.
