NBA Legends Chris Mullin & Mitch Richmond -- Reunited ... For Frozen Yogurt

Ex-Golden State Warriors Chris Mullin and Mitch Richmond took it to the hole yesterday in L.A. -- the holes on their faces ... and we got video of their frozen yogurt get-together.

The two basketball stars were hanging outside of Menchies Frozen Yogurt in Calabasas and told us they're "friends for life" who kick it all the time.

Check out the video to hear their thoughts on modern day basketball and the perks of retirement.
