The Grizzlies have unveiled three different billboards featuring O.J. Mayo in Phoenix as part of their Rookie of the Year campaign.

The billboards are in conjunction with the launch of voteoj.com.

"The great city of Memphis is fortunate enough to see O.J. Mayo every day, and we wanted to help share his basketball brilliance with the entire NBA community," said Greg Campbell, Memphis president of business operations. "We decided that there would be no better place than Phoenix, with the national spotlight on All-Star Weekend to debut O.J.'s Rookie of the Year campaign."
