didn't know you posted a vid until you mentioned it.
1) camera man sucks. lol. the constant shifting never lets the camera focus so you're blurry... unless you guys are ust insanely fast
2) if he's going to use a boxing stance where he's turned tot he side, just low kick the shit out of him since he has no way to defend. once he starts respecting the low kick, fake, then high kick him in the head.
3) put on shin pads and 16 oz boxing gloves. those gloves look too small to swing with respectable force. if you don't respect the punches, you won't learn to defend them. you need to get bopping people and get bopped back. maybe you were but it was hard to tell. all the kicks were less than half speed because of no shin pads. you don't want to get in the practice of throwing half-assed.
4) you duck your head a bit and get to worried about the goofy shit he was trying to throw. do your thing. cut him off in angles and step in for your combos and pop out of range when you're not throwing. get used tot his and fake to step into range and see how he reacts, but actually pop into range and unleash a combo.
5) not bad at all. once you step in, you start turning your stance from square to a side boxing stance like him. if someone double legged you or low kicked you, you know what's going to happen.
the hardest guys to fight are the goofy random guys because you can't predict the shit they're about to do. in a month you'll pick this type of guy apart with just the boxing/MT basics. straight punches, hooks, and mt kicks, quick sting jabs would pick his game apart.
also, he looks every uncomfortable when you get close to him. get close ad nasty and dirty box him. he's probably not used to this and these is where you can use your strength and posture to push him around. watch randy couture get up close on someone.
summary: bigger gloves, shin pads, and a new camera man.
