OK, so the first 8 videos are of Bristol Marunde. 1-3 are full fights, 4 is HLs of a fight, 5 is the finish of a fight, and 6-8 are 1 round each of a 3 rnd fight.
Basically, he's a striker that occasionally surprises with a decent takedown (typically catch a kick & sweep or duck under punches for a blast double). Technique's OK when he's fresh, but tends to start flagging about mid-way through Rnd 2. Only submission showcased was a nasty looking Kimura from side control.
