I am speaking in general terms on this, but in my opinion, the three hardest positions in sports are: hockey goalie, MLB catcher, and NFL QB. I cannot imagine trying to stop a hockey puck from coming in at that speed, not to mention all the traffic that comes in front of the net. I played catcher briefly in minor league baseball, but to be a catcher in the Major Leagues seems extremely difficult, especially on pitches that miss the mark or that have such movement on them. Lastly, the NFL QB position has got to be so difficult. I think of all the QB's who are good in college, hell even great, and when they make it to the pros, they just cannot cut it. The speed of the game, the playbook, and the competition level—I wouldn't want any parts of those three. Anyone have another take or position to add to the list?
