Difference Between Rugby and American Football

In preparation for our upcoming Superbowl viewing party I thought I'd share the differences between our two sports as told by Stubhub and http://www.diffen.com/

It is never right to plagiarize kids, none of this information was written by me!

American football is a game played between two teams and consists of 11 players in each of the two teams, with unlimited substitutions. American football is a game of intense physical play with complex strategy to score points by advancing the ball to the opponent team’s end-zone.

Rugby is best described as a blend of the contact of American football, the running of soccer, and the transition of basketball. It is a game played between two teams with 15 players in each, played on a rectangular field, with the object being to run with an oval ball across the opponent’s goal line or kick it through the upper portion of the goal posts.
