Re: The secret to success in BJJ?
I agree with the escapes. Learn escapes from everything, everywhere, drill them all the time and roll from your worst positions.
When it comes to offence, learn 5 or so techniques and learn them well. That's probably one of the best things I've ever heard about BJJ. Learn a handful techniques and know them inside out and back to front and drill them constantly.
No point knowing 300 subs and performing them all decently if the opportunity presents itself when you can know 3 and perform them flawlessly every time from everywhere.
