TJ is amazing. I feel that hes reached a level of fighter that we have rarely seen in MMA. Having said that, I think TJ might be a better match up for Henry than DJ was. Henry had problems getting his hands on DJ and when he got his hands on him he had trouble keeping his hands on him. That's because A. DJ is tiny. He has a very small frame. and B. DJ is incredibly fast and quick-twitchy. Every movement executed by DJ is done with maximum speed and he can fire off multiple movements in rapid succession. It s hard to hit a guy like this and hard to grapple/wrestle a guy like this. So all that considered, Henry did an outstanding job.
TJ, while incredibly skilled and well-rounded, is bigger than DJ and not as quick. Sure TJ has great movement and timing, and he can pull the trigger quickly, but he doesn't have that same kind of speed that DJ has. There is also other factors in TJ's style that may allow Henry to beat him. TJ has extreme confidence and a desire to finish. Because of this, TJ will engage Henry in close quarters more than DJ did in the rematch, he will evade Henry less, and Henry will have more chances to wrestle and land punches in close.
Its a very tough fight for Henry to win but he certainly has a decent chance (At least).
