This is what drives me nuts about the "no rules/dirty fighting" crowd.
A boxer practices his right hook day in, day out. He's drilled it on bags, pads, and sparring partners that are fighting back, hard. Some of them are larger, stronger, faster, etc. He's thrown that hook, and connected, hundreds of times, in high-stress competitions where the other guy was trying to take his head off.
He knows that, when necessary, he can rely on that hook.
A judoka practices his O Soto Gari day in, day out. He's drilled it every way possible, shadow uchikomi, to therabands, to throwing partners on the crash-mats. He's smashed heavily resisting opponents with it in randori and competition hundreds of times, usually in a state of extreme stress and exhaustion.
He knows that, when it matters, he can rely in that O Soto Gari.
Some of these TMA/Krav guys read dirty fighting tips from weirdos on the internet. They go to their club and, since they don't spar, they practice these moves on imaginary people they envision in front of them while doing their kata. Sometimes they act like teen-agers and play "pressure-point ass-grab" with each other.
When shit matters, they are going to be relying on techniques that they have literally NEVER pulled off.
It's fucking retarded.
