Munk, good points for sure, and Van. But you don't need to train in fighting dirty to know how to fight dirty. Granted, boxers might tend to box, but that's not to say that they'll always forget to headbut a guy. And I too advocate the leg kick, thai clinch etc., elbows, knees etc, all of which I throw on my bag to keep a basic foundation. But again, you don't have to be an expert in TKD or MT to do those things.

Also, you're right about judo. IMO, when it comes to the clinch where the boxers fists are partially neutralized, I greatly advocate judo or even GR wrestling.

But I still agree with D. Yes, our 99% might be a bit high, but it's not too far off because in terms of having ONE base, boxing (yes, intertwined witha few others) is most of what you'll need.

and here's a big part of why: a decent boxer has two hands to use. The average chump has just one, and it usually aint even that good. The aveage chump would fold like a tent if you planted a bare-fisted body shot on his ribs.
