Diego has a chance unless he tries to box or grapple BJ. As long as he circles and dodges jabs, he'll do okay. But as soon as he stands and bangs with BJ, he will find himself unconcious because he is no match for BJs boxing. And as soon as he shoots in for a takedown, it will either be stuffed and end up with BJ on top or he will succeed and end up in BJs guard. Eitherway, he will find himself finished. I'm a fan of Sanchez's fighting style, don't care for him at all, but I like his aggressive, attacking style. But his style is what will get him rocked with a counter and finished on the ground.
