I've always felt that Ground and Pounders were guys like Tito, Matt Hughes, Coleman etc that use their wrestling experience, tremendous strength and athleticism to get their opponent to the matt and beat them senseless. Obviously the Gracie's have shown over the years that an opponent that has no BJJ training is very susceptible to a submission regardless of weight advantage. It seems rare now days in MMA to see top fighters that are true submission artists. They all have training in it and if an opponent makes a mistake can submit him but you rarely see a fighter consistantly looking to finish a guy with a submission. Only noguiera from pride really comes to mind. BJJ's real asset is the abilty to fight from the bottom and win. All fighters train in it but with the evolutoin of MMA it is not necessary to be a great BJJ artist just good enough to defend against it and escape.
