Old timer? If ANYone, Randy Couture would be the one to pull it off. And there's a big difference between Royce Gracie/Ken Shamrock's prime and Couture's prime, because his came way later when he was already in his 40's. Shamrock and Gracie should have retired before they turn(ed) 40. Hell, Couture would STILL be the more complete fighter in his 50's compared to Shamrock and Gracie in their prime. It's just not a good comparison. Ridiculous, if you ask me.
