If people dislike Tiger for cheating on his wife. They should dislike Sean Payton too.
agreed. there also comes a difference in team vs. individual sport. in golf, you are fans of players as they are basically an entire entity in the sport. you are a tiger fan. you are a mickelson fan.
in football and most other sports, you are a saints fan. you are a falcons fan. so while you might not like sean payton, you still like the saints and want sean payton to do well because he runs the team that you like and you cant control that. you probably want a coach that doesnt cheat on his wife but you arent gonna stop liking the entire saints organization because of one guy. in golf that one guy is everything and you can easily not like him and switch "teams" to another golfer.
