Not sure what background either the 2 guys in the fight at 13:00 in the 2nd vid come from, but I doubt it's one with much grappling.
The guy in red is almost fighting TKD style with quick kicks and a low guard, grabbing onto the guys gloves when he comes in for a clinch and holding on for dear life.
I've gotta say, I prefer the vids i've seen of the European fights, with guys like Muslim Salihov. This is still good, but the guys like the Russian fighters seem to have better fundamentals.
I mean, in the first vid, the guy in black dropped to one knee throwing a wild hook, losing points in the process
EDIT: just realized that Salihov is in the 1st vid, oops
