Yeah, the Demain Meia fight was very interesting. Lots of action, and interesting use of the gi for a choke! I didn't know you could do that, either.
The Marcelo fight was pretty boring. Perhaps that reflects a somewhat higher skill level? Ie; small positional adjustment could lead to an instant submission, so they choose not to move until they are dead certain they can do so without getting tapped.
