I'm with Mushroom that even though any good wrestling fan knows the Austin-Bret feud, the peak of the attitude era saw Austin going against The Corporation which was Vince and Rocky and that's what the mainstream fan remembers when they think of Stone Cold.
Stonecold's highest mainstream publicity happened when he was going against HBK and MikeTyson
and the biggest drawing match between rock and austin happened when rock wasn't even in the corporation
you're giving corporate rock too much credit in "building austin"
