Austin did lose momentum and it affected his career standings in terms of whether he would be looked at as the greatest of all time
at his peak though, he was bigger than any wrestler ever...
i think his performance towards the end of his career and coming out and doing the drinking, the what, the oh hell yeah over and over and over for what seemed like 5 years hurt him in a long term persective as well...
his character was perfect, the ultimate bad ass, and they did kind of neuter him after the heel turn and then turning into a more comedy figure... it ruined him imo.
he was on pace to be the GOAT
