What is the hardest role in an any sport?

Had an interesting discussion about one of the hardest position to play in any sport. But then we got to talking about the hardest role to play.

Yes being a QB in the NFL is hard, cornerback is hard, goalie in ice hockey is hard.

What we’re discussing is complete role in any facet of the game. For example; Is being a QB for the Dallas Cowboys the hardest role? A goalie for the Edmonton Oilers, a closing pitcher for the cursed Chicago Cubs (before they won obviously). Maybe even a coach?

Let’s hear it.

had to attach something for the post, sorry if i’m amateur. Added some of my own flair*****
