Who will you talk about

For anyone that has been watching the evolution of MMA, there are likely a few guys that have a signature move you will always remember them by. Or a move that you will think back about in 20 years when we are all still posting on Sherdog.. LOL

First guy I think of is Shamrock bringing the danger of ankle locks when they had never been seen by most.. Who do you think of or will you tell our kids about..
