Yeah, Marcelo's escapes are awesome. The real problem is that you have to be as quick as Marcelo and as fluid and explosive as him to land them on an opponent a lot larger than you (at least, with that particular body-lock reversal). I have a hard time pulling that one off.
Totally true. IronMan, have you seen the escapes series with Marcelo Garcia (it's about bridging). He shows some pimpin' escapes there (and yours is ofc one of them). There's one when you grab a bodylock, bridge to get your hips under your opponenet and then reverse him that just looks beautiful. Too bad I drill far too few sidecontrol escapes...
Plus, I like going to the back, as I find I can transition to a lot of dominant positions from there with a lot more ease, and I never end up in my opponent's guard when I have control of the back. At least, not in one move.
