1.There was no destruction. Dodson dropped him and was the beneficiary of one of the most outlandish stoppages I've seen after following this sport for a decade. It was an outright joke and the revisionism annoys me.
2.TJ has progressed eons from that point, far more so than Dodson has, and there's a pretty good reason: he had 4 fights. 4. JD had 16. His movement and overall striking prowess on Saturday looked noticeably better since the Easton fight, never mind the TUF finale.
If TJ holds the belt for a while and Dodson loses another title shot I wouldn't be surprised in the least to see a rematch formulate quickly.
