Damn bro.
I'm backing Page here too but only got a small position.
It takes Chute Boxe type violence to TKO Rampage, something Forrest doesn't have. Page is strong but Griffin is a huge LW. His best chance is to wear Page down with his size and take over in later rounds. Considering Rampage showed a lot of grit and determination in his fight against Hendo and went the distance, I think he's proven he can handle this too.
Forrest likes to stand and trade. This was fine when his opponent Stephan Bonnar but not so much when it was Jardine. Rampage should be able to catch Griffin eventually in these situations.
Good luck Pike.
