I agree Aaronyman, he has a very reckless striking style. Not that it's a bad thing for some fighters, but not the greatest choice for him.
He hasn't learned how to be able to get any real power out of his punches and still leaves his chin out there when he's swinging. You really need to either have one punch KO power or a well protected chin. He has neither. Tons of heart, but that only helps when you can open your eyes.
Don't get me wrong, I really like Forrest, I just don't see him holding on to the belt long unless he REALLY tightens up his stand up.
I don't see him gaining too much more power in his punches, so I feel he needs to learn to protect his chin better while punching. He really has a good ground game, maybe he needs to be focusing on that more and more if he wants to keep the belt for a while.
