8. Jeremy Horn (24 losses)
Jeremy Horn is by no means a loser, though he has lost a lot of MMA fights. While he has 24 losses to his name, he’s also fought 120 times. His losses also haven’t been too damaging, as only 2 of those 24 came by way of the knockout.
Horn specializes in submissions, and often his fights end up being straight grappling and submission contests that are conducted under MMA rules (whether that’s what his opponent wanted or not). This also makes it easier for someone like Horn to fight often, because he is enduring little damage during the fights.
All the same however, 120 fights is pretty ridiculous, and to have had the kind of success he has had is unprecedented. If Horn continues to fight into his 40s, its not unthinkable that he could top the 100 victory mark.
