Before every fight Diego and Team Jackson say he has become a changed fighter lol. I can't remember what fight it was exactly but his stand up had improved a lot and he actually did look like a better fighter. That was a long time ago, I think it was after his loss to Fitch. Since then it seems he does nothing to change his style to become a top contender again. Every fight he comes out swinging, whiffing almost all of his strikes, and rarely going for a take down. I really think he has the skill set to beat Pearson if he has improved his striking and mixes in take downs. If he tries to brawl he will get picked apart to a decision so he needs to throw in some take downs. Either way this will be an awesome fight regardless just because Diego brings it, win, lose, or draw.
