Comedy star Brad Williams says Blake Griffin could easily go from setting screens to setting up jokes now that he's retired from the NBA ... telling TMZ Sports the former hooper is legitimately good at standup.
Williams said out in L.A. on Tuesday -- just hours after Griffin announced he was hanging up his basketball sneakers -- that he's seen the ex-Clippers forward rock the mic before ... and he's been seriously impressed.
And, Williams told us if Griffin uses his newfound free time to really commit to standup -- he could be a real player in the comedy world.
