Melo recently went toe-to-toe with his former teammate's son, KJ, when the Lakers played the Houston Rockets on Sunday and Tuesday.
The Lakers star said it was a special moment ... and, when we asked Martin how he felt a few days after, he says it was awesome, but odd at the same time -- praising Melo for still ballin' in the NBA at 37.
"It was dope," the 43-year-old tells us, "Strange feeling at first but testament to Melo for one."
"His longevity in his craft. Still playing at a high level."
