Rugby vs Nfl Athleticism - Top 10 Sports

This one will come as no surprise to people who have played both sports, but rugby makes significantly more demands on your lungs than American football. Not only is the action mostly non-stop, but there are very few points in the game when a rugby player is taking a break; they tend to run for almost all of the 80-minute match. Compare that to football, where the average game broadcast is three hours long, but the ball is only in play for an average of 11 minutes. And you linemen: we love you, but try keeping those guts and running non-stop for more than an hour per game -- it ain't happening.
