Otavio Sousa is one. Click HERE.
Add Roberto Satoshi to that list as well.
I stumbled across this match today, and it reaffirms what I saw in the Otavio Sousa Copa Podio match, Leandro is susceptible to the sit-up guard type of standing up for a single leg type takedown rather than a traditional sweep.
Jump to the 2:30 mark in the midst of the scramble to see Satoshi get to his feet with the pants leg grip and then ultimately finish on top.
This sit-up guard sweep is a mainstay of guys like Otavio Sousa and Rodolfo Vieira.
See BJJ Scout for further evidence.
