In the beginning, point fighting was hard to do because the rules were so crazy and the sport so new. Fighters just got stuck in positions or couldn't match an opponent's movement.
Then Miletich came along and fighters started specifically training to win on points. MFS fighters were notorious for this, but I think Tim Sylvia benefited the most from this training. It's what allowed him to be one of the UFC's HW greats (by title defenses) for a decade.
Various strategies had their time in the limelight: lay and pray, wall and stall, the Machida era, and probably others.
i'll be honest: this isn't a part of MMA I ever really paid attention to and I know damn little about it.
What dominant point-fighting strategies emerged? Which fighters pioneered them or took them to new heights? Who looks like they're going to be the next great point fighter?
