"If you're going to go out and you want to say all this stuff about the UFC, we know what we are, we know what we do, we know what you've been paid," White told MMAjunkie.com (www.mmajunkie.com). "OK, you made $15.2 (million) but you wanted $100 (million). It's always going to be the case."
In support of the event, Jackson (32-10 MMA, 7-4 UFC) played a video game and gave short answers to the media at the UFC on FOX 6 press conference.
"To come up here and treat the media the way he did, it's professional suicide," White said. "'Rampage' has the ability to be a huge star. We've seen it. When he's on and his head is right and in the game, there's no one more entertaining. There's no better press conference to be at."
Some MMA fans think Jackson is just playing hardball with the UFC, but White thinks Jackson is seriously considering a move to boxing.
"When you look at this situation and where 'Rampage' is right now, mentally, and all the things going on with him, you can tell there's absolutely no pressure or stress on 'Rampage' whatsoever. It's another fight for him. He honestly believes 100 percent that he's going to go box or whatever he's going to do.
"For Glover, all the pressure is on him. This is, I'm sure, the most nervous he's ever been. It's a career-defining moment."
