Thesz is the only pre-WWF era guy who stands a chance honestly, and even then, that took Gelgarin lobbying for him annually.
As far as the entrants go, Lesnar getting seeded over Hogan, Cena, Bruno, Rock and Thesz? Really? I'd have Lesnar in my late teens/20's most probably. HBK is also a little high for my liking, but that's a little less egregious.
