On the face off it, the UFC getting Brock Lesnar to agree to coach on the 13th season of The Ultimate Fighter is a home run.

He’s already the biggest pay-per-view draw in the sport by some distance, able to pull in over a million buys for shows he headlines. That should translate into a ratings boost for The Ultimate Fighter on Spike TV, and it could send the PPV buyrate sky-high when Lesnar and Junior Dos Santos eventually meet in June.

So far, so good, but there’s a potential downside here that Dana White is well aware of.

“It’s going to be – I’m already prepared for this, mentally – it’s gonna be a tough season. I know it is. I know it’s going to be a tough season. I deal with Brock in very short spurts. The guy fights two or three times a year, and it’s always tough. It’s going to be a very interesting six weeks of filming,” White admitted during a conference call yesterday.

Basically Brock is a highly volatile character who doesn’t like dealing with the media, doesn’t enjoy being followed around by cameras, is not a ‘people person’, and isn’t comfortable being away from his home and family for long stretches at a time.

Therefore six weeks of coaching TUF which will involve all the aforementioned factors and more is almost certain to be a living hell for the former champion, and will more than likely bring out the worst in him.

Now that could make for great television as Lesnar rants, raves and breaks an unprecedented number of doors during the season, but there’s also the risk that he might just down tools and quit.

“In dealing with Brock, one minute, he can be into something, and the next minute, he can completely be not into something,” says White, hinting at the potential for trouble at some stage down the road.

One way or another, with Lesnar involved there’s bound to be drama at some stage, and that’s going to make the 13th season compelling viewing when it begins airing on Spike TV on March 30th.
