Brock is someone to look up to, he played Nfl football DT for the Vikings, then went to wrestling and then ufc, it just tells kids they can do anything they want if they try.
No, he wrestled, then used his WWF fame to get a short-lived(and failed) NFL 'career'.
And as far as being a role model for kids, flipping off the fans who are booing you and then saying you're going to go "bounce on your wife" isn't really acting the way professional athletes are supposed to.
