"New Girl" star Lamorne Morris is sick of Bulls fans dissing Derrick Rose for getting injured (again) ... telling TMZ Sports even a gimpy Derrick is still the Bulls best baller since MJ.
Morris was out at Warwick nightclub in L.A. Wednesday night when we asked the Chicago native and huge Bulls fan about the Windy City's reaction to D-Rose's latest injury setback.
It's been pretty bad for Derrick since it was announced he'd have to have ANOTHER knee surgery, with memes, tweets, and IG posts all slamming the injury prone superstar.
Check out the clip -- Morris goes off on anyone taking Rose to task, reminding Bulls fans just how much the team sucked after Jordan left, and saying the city is lucky to have him.
BONUS -- He gives a pretty dynamite Stephen A. Smith impression at the end of the video, you'll want to see it.
