Busta Rhymes: PUMPED ABOUT DERRICK ROSE ... Not Pumped About Porzingis

Here's the summary of this video -- Busta Rhymes LOVES Derrick Rose. He LOVES Carmelo Anthony.

Porzingis?? Not so much.

Busta is a huuuuge NY Knicks fan -- and says the combination of D-Rose and 'Melo is a major step in the right direction for his beloved squad.

But when we brought the other star on the team -- Kristaps Porzingis -- Mr. Rhymes didn't seem too enthused about the Latvian sensation.

"Carmelo and Derrick Rose ... and I'll vouch for that. I ain't vouching for nothing else."
