Toughest job or position in team sports?

[Kite Triblade]

Im just curious what would guys say is the hardest job or position in team sports I personally lean towards being a Quarterback in American Football or a Goalkeeper for Team Handball

I say them two sports as to me it is quite a dependant role as if that position plays bad it can wreck the whole teams motivation and score

I might be slighty biased as Im currently the goalkeeper for my uni handball team and its tough work as the shots are thrown in with a ton of power and it can be quite demoralisng that our save percentage is not expected to be high around 35-50%

As sports progresses...I think the quarterback position is going to become a lot more difficult to play, as it's a changing role. One has to be fast, intelligent, agile, accurate, and elusive. It's a position with a lot of pressure.
