Is it his committment level? I think a lot of fighters get a sub and slowly apply the pressure to get the tap, where as Mir cranks it not caring what the end result is. Also what separates elite takedowns from a lot of mma guys? Guys like GSP, Frankie, Mendes and Chael drive at you like they are Goldberg trying to spear your ass. Where as a lot of guys reach and then try to pull you down as opposed to mowing you over? Not a techincal discussion but is that the basis on why a guy like Mir is so deadly with subs and other guys with their takedowns is that they are going all the way through?
