How much of an edge woud the best players fold early?

Thinking about Hellmuth's 4-1 comment, I ask this question:

First hand of the tourney. If you take some of the best players in the world like Lederer, Bruson, Ivey, Hellmuth, etc. told them what everyone at the table had for this hand. If a person went all in and the superstar pro was a 2-1 favorite, would he call? What about a 70% favorite? How much of a favorite do you think the top pros would have to be in order to call all in on the very first hand of the tourney.

Or heres another somewhat similar question(perhaps Annie or Barry can chime in here): You hold QQ on the very first hand of the WSOP. Some unknown internet guy goes all in from EP. Do you fold? What about if you hold KK in the same situation?
