Too Short Not Backing Jon Gruden, I've Got Mixed Emotions!

Too Short ain't exactly throwing Jon Gruden a vote of confidence ... telling TMZ Sports he's legit torn over the way the Raiders head coach is dismantling his favorite team.

We got the legendary Bay Area rapper leaving Sirius in NYC on Tuesday ... and he made it clear right away -- he ain't pleased with what's going down in Oakland.

"I'm really mad about 1-5," he says as he showed off all the silver and black he wore ... "I'm pissed about that."

Short's biggest problem with the team? Gruden ... 'cause Short says he's got some serious mixed feelings over Chuckie's first season back as Raiders head man.

"I'm just like everybody else, I'm mixed in between trading away all our players and bringing in the coach that beat us in the Super Bowl ... it's just we all got mixed emotions right now."

Short says it's gotten so bad for him ... he's legit on the verge of tears!!!!

But ... he does have one saving grace that he says makes him feel better ... "the Warriors, man!!"
