You’re right. MMA fighters also tend to mostly come from grappling backgrounds, so they would have only started doing boxing or kickboxing much later in their careers.

because in MMA its greatly beneficial to square up more to your opponent to help stop takedowns. If you fight in a typical 1 leg forward boxing stance with one leg out in front of the other it makes it more difficult to avoid takedowns as you’re leaving a big target for wrestlers out in front of your body. To negate this you have to have a very fast sprawl and have enough power and good enough boxing/muay thai/kickboxing to make it worthwhile to risk leaving your leg out like that.

Arlovski has decent hands and a lightning quick sprawl so he’ll fight less squared up in a more traditional stance (if only he wasn’t china chinned). Anderson Silva often fights 1 leg out but that’s because his most dangerous weapon is knees from the clinch so when somebody shoots on him they are just as vulnerable if generally not more so than he is… Prime Mirko Crocop Filipovic was an example of a standup fighter that was able to compete in MMA while fighting in a boxing/kickboxing stance instead of squared up because his sprawl was even better than Arlovski’s.

Man…i forgot about Norton-Cooney Jrok. Ya know i dont know which one is the worst. I mean Poor Ken was almost sat down on bottom turnbuckle and taking monster uppercuts.
Perez seems to be one of these refs that forgets he is one and just watchs..
