There's fights they lose 4 rounds and win in the last second, there's fights they win all rounds and lose in the last seconds. For me those aren't losses or wins really. I judge how superior they were in each fight or how they deal with back and forth bouts. Also the losses affect them more mentally than physically, there's no way you're a worthless fighter because you lost in MMA, what matters is your comeback. I like when they lose and come back stronger.
I don't care much about the record, can you say Rory is a loser after the rematch with Robbie Lawler ? or that Anderson took a beating from Bisping ? nowadays their record probably speak a lot, a lot of casual fans judge that. but i don't care much, most my fav fighters have losing streaks in their records.
