the submissions is the most exciting part...the fact that it takes so long makes it exciting...it's like watching a chess match, you need to plan every move ahead and anticipate what your opponent is going to do...one minor slip, arm slightly out too far or neck angled wrong and bam, you're submitted
another reason why Gracie can't stand a chance anymore is, everyone started learning brazilian jiujitsu to add to their standing combat style...unless gracie learned some thai kickboxing or something, he'd better get hughes down to the ground quick
5 minute rounds are still ridiculous though...we used to do 2 minute rotations of grappling, and after the first 2, you'd be gasping for air
