It sounds ridiculous that a 50 year old Lesnar would still be fighting in the Octagon 10 years from now but consider this.... - Lesnar likes money. He LOVES money. And he's willing to take some pain to get that money. - Lesnar will probably not be fighting for the WWE in 10 years, his OTHER source of money. And even if he still is, the WWE is permitting him to take fights in the UFC. I don't see that changing. It's win/win for both organizations. A high profile real-life fighter lends credibility to the WWE, and WWE's rabid fanbase follows Brock to the UFC. - The UFC know's he's a bankable star. He's a proven box office draw win, lose or draw. He's such an oddity that I don't see his popularity declining, even after 10 years. PEOPLE WANT TO WATCH BROCK LESNAR. They can always count on him to take a one-off fight, even if it's just every couple years. - PED's or no PED's, they will always find a way to use Lesnar. He's getting a title shot after returning from a PED suspension and hasn't won a fight in almost 8 years, for God's sakes. I wouldn't be surprised if he tested positive this fight. Then the next one. Then the next one. He'll continue to get exemptions, take the money and run, and return after these suspensions. - The UFC has shown they don't care HOW they use Lesnar or if it affects their reputation. He's money, and that's clearly where we're at with the UFC. -I know 10 years is a long way's away, but guys like Couture and Coleman fought deep into their 40's and they didn't have NEARLY the drawing power or magnetism that Brock has. BJ Penn fought years past his prime and we watched. So has Wanderlei and a host of other guys that should have hung it up years ago. If they were still draw's, don't you think they would still be getting regular bookings?
