Terrell Owens might be 43 but it's hard to tell from his hoops game ... 'cause judging by this video TMZ Sports got of him ballin' in L.A., the guy still has it.
T.O. was balling up at the Sports Academy in Thousand Oaks, and showed flashes of the athleticism that's gonna make him an NFL Hall Of Famer one day (seriously guys, put the man in).
Peep the clip ... T.O. calmly drains a three off a sick assist from the guard ... then darts up the court and straight Mutombos a shot from a guy who obviously hasn't read his scouting report.
He's still moving pretty good ... just sayin', NFL GM's.
