#3 Reputation
When Brock Lesnar was preparing to face Cain Velasquez for the UFC Heavyweight Championship, his MMA record stood at an impressive 5-1. The guy was one of the most dominating figures in the entire sport and his reputation was growing with each passing fight, as more and more people realised just how great of an athlete Brock really was.
But when you fast forward to the day that he first left the UFC, his record stood at 5-3 following consecutive losses to Velasquez and Alistair Overeem. Given his health, Lesnar's reputation in the sport was starting to take a bit of a beating and the logical thing to do was to walk away whilst he still had a winning record.
The heavyweight division was on the up, and preserving himself was a great move on Brock's part.
Onto a slightly more controversial entry.
