Let me preface the story with the following: I do not think or wish for Brock Lesnar to retire if he were to lose to Junior Dos Santos. The storylines, exposure and fights he provides are an MMA fans wet dream. To see him go after eight fights would be terrible.
But I can totally see it happening.
Lesnar's quirky personality leaves pretty much any option open. I could see him taking a year off, training like a mad man and coming back better than ever. It's plausible that Lesnar runs away to the woods of Manitoba, never to be heard from again.
So why should Lesnar retire in the case of a loss? Look ahead to find out.
