Only two guys I can think of are Charles Oliveira and Ricardo Lamas. (both black belts) Charles Oliveira is great with his submission offense, BUT his defense is not that great he got submitted by Pettis and Lamas. Plus to that he can not make FW limit anymore. Ricardo Lamas is great with sub offense, AND is also great at defending chokes. So Ortega vs Lamas interests me the most. Anybody else who comes to mind?
