Why do people ume that they could beat Tiger Woods up in fight just because he is a Golfer?

When Woods was at Stanford, he, and all the athletes, were tested for strength and compared to body weight. Tiger Woods was the strongest, pound for pound, of any athlete in any sport. (I wish I could supply the link, it was in Sports Illustrated, maybe 10-12 years ago). I think he would avoid a fight if he could- he's a gentleman, but if cornered and the options to avoid were not there, he would kick some serious , I believe.
