Team Quest and all of those arent really grapplers. In reality grappling does not exist yet. Their is only submisssion wrestling. No one (this is a soapbox for me as this is EXACTLY what I want to do) has developed a world class wrestling game with a world class BJJ game. Look at arguably the best grappling competitor around - Jeff Monosn; his bread and butter is BJJ and pure strength. Randy Couture made taking Tim Sylvia down look easy - Jeff Monson shot one dimensional double legas to get sprawled on many many times
The guys as Team Quest and other Wrestlers have developed a perfect adaptation of Wrestling to the ground. They use good chokes but they are usually modified headlocks and they cant really pass the guard and their knowledge of armlocks is rudimentary. They know how to defend BJJ perfectly and apply their wrestling. That is an art form.
