So true....... I learned that the hard way when I was younger lol. Boxing is all fine and well, until you end up with someone who can grapple lol. Grappling ( just my opinion here...) is probably the best all around street fighting skill there is.
While it's true, most street fights go to the ground, and ground fighting is important, it's really best not to go to the ground on the street. There's way too much that can go wrong. If you can box the best thing you can do is end it fast so you can walk away.
