This is what happens when your train your whole life in a specific school of combat and never actually put it to the test by taking on someone who actually aims to hurt you. p.s. LOL https://www.youtube.com/watch?v=bxb0PCBV0vk
Ummm the Aikido master was old as shit, understandable that he went down easy. Aikido can be used effectively in MMA (see), but you would only be a fool to believe one style is better than all.
To be accurate, this is what happened to that guy who trained in a specific school when he took on the other guy who actually aimed to hurt him. Saying that is kind of silly, really. One guy wins against another guy. That doesn't mean the winner knows a better form of fighting. It simply means that guy is better than the other one. Could another Aikido master (a real one) beat that guy? Probably. Could another MMA guy beat that real Aikido master? Probably. No matter who you are there's someone who's got your number.
