Baron Davis is turning to one of his former NBA teammates to help him win a Mirrorball Trophy this year -- telling TMZ Sports he's getting dancing advice from none other than Iman Shumpert!
Just hours after it was revealed the former Golden State Warriors point guard would be on the newest season of "Dancing With The Stars" ... he told us he's already picking Shumpert's brain on how to two-step through the competition.
Shumpert, of course, won Season 30 of the show -- and Davis said Wednesday the guys have already FaceTimed to talk strategy.
