Not all UFC fighters hate Conor McGregor -- despite what Cowboy Cerrone said this week -- but there ARE a bunch of guys jealous of Conor's huge paychecks ... so says Dominick Cruz.
Cerrone told SI Now that "all" of the UFC fighters hate McGregor -- "He's not one of the fellas. He's not a good dude."
So, we reached to Cruz -- who knows just about everyone in the UFC -- and asked for his take.
"I think what they're upset at is the fact of how much money he's made, how quickly and on his own," Cruz said.
"But that doesn't make ME hate him. That makes me try to understand the situation and make a better situation for myself."
"And to me, hating somebody, being bitter at them for making more money than me, that's only going to hold me back from doing what I want to do personally."
Smart dude -- watch the clip.
