It doesn't make him any worse, it just means he no longer among the best statistically in that regard. I feel I should also point out fightmetrics top 10 requires 20 TD attempts on you before you're eligible so a large number of (who I would consider to be) the elite in that regard aren't featured. Cormier, Teixera, Weidman, Barao and the like. There are also an absurd amount of excellent wrestlers at WW who, while not possessing a better TDD%, I would consider better. The only reason they aren't higher in that table is that they've all fought each other and taken each other down. Hendricks, GSP, Woodley, Kos, Story, Ellenberger, Pierce, Jason High. I'm sure there are others I can't remember too.
