Forrest is a grinder, with a ton of heart, great chin. Not the most athletically inclined. As MMA becomes more lucrative, you will see better and better athletes. The challenge with gifted athletes, no matter what sport is desire. Look at Michael Vick. He admitted he half heartedly tried during his career, and he did so because he could. Someone like GSP, Anderson Silva are fighters who are stud athletes and have applied themselves to making themselves the best they can be. Silva got his black belt in BJJ a couple of years ago from Minotauro. He filled the hole in his game. (A former Chute Boxe fighter with great stand up, but suspect sub defense). GSP is constantly improving, and showed tremendous heart in the Alves fight.
Forrest will always have a place in the UFC because he brings it. He was winning the Evans fight before Rashad got the takedown and finished him with a brutal GNP. Guys like GSP, Anderson, Machida, Lesnar, BJ are the new breed. Great athletes with complete skill set and little holes in their games.
