Heart is something in fighters you will never be able to measure and it is the reason why Randy Cotoure is loved and so successful. Forrest has heart but it will only give him enough courage to get in the Ogtagon against "the #1 LHW in the world". After the shut that cage door, you can have heart sit right next to Rogan and Goldie cuz it will help him as much as they can. Heart comes into play when a fighter is a LITTLE less in hieght, size, or speed. Sometimes even if a fighter is a LITTLE less in talent but the margin of talent between these two fighters is so big heart will get lost in the arena on the way to the cage.
