So soccer helps you with stuff like this? There is always benefits but it isn't hugely beneficial. Jon has great kicks and he doesn't play soccer.
No soccer doesn't help you with a back kick but it certainly helped Aldo with his famous low leg kick. And by the way Jon does not have great kicks. In this pic his form is not good. Jon is definitely improving with his kicks but far from a great kick. Aldo, Pettis, Barboza are "great" kickers not Jon.
