I would say NHL goaltender might have more pressure than QB. Extremely hard to win if your goalie messes up, poor goaltending has sunk many an elite team. You still have your defense and running game to fall back on if your QB isn't up to par. And of course the pressure of an individual sport is another level up.I avidly follow all four - NFL, NHL, NBA and tennis.
I couldn’t disagree with the assessment the best all around atheletes probably would be found in basketball. And I wouldn’t have an issue saying that the QB position in the NFL is probably the most pressure filled in all of sports.
But somehow, in spite of all that, Federer to me has become the most impressive athlete in my time.
