age is already catching up with him, dirk smoked him in the playoffs, and i know dirk is 7'0 but bowen used to keep nowitzki in check in the past spurs-mavericks series, he obviously cant do it anymore.
he still has atleast another season or two left. his main priority is defense so he can push it a little longer. i say 2 years, 3 tops. iam hoping the spurs find a raw talent soon and have bowen mold him into a perimeter defender while he can still play.
