Devin Funchess has successfully made the transition from NFL player to pro hooper ... but he tells TMZ Sports he's not done yet -- he still wants to make it to the NBA!!
The ex-Carolina Panthers wideout has been training for years to establish himself as a big-time baller on the hardwood ... and so far, the journey's gone well.
He's played overseas at a few stops ... with his most recent contract coming from the Colombia Basketball League -- and he says he's pleased with how the new career's going.
