Are You Ready for Some Football?

In preparing for a group project tomorrow with high schoolers I realized that if I was going to help them make a giant football field for their class I'd better know some football terms...
Google to the rescue!  Here's a good site for quickly reviewing the dimensions of the field, plus the positions of the players.
Fan's Guide to Football
Another page on the site provides a glossary of football terms.  I'm going to memorize a few of the lesser known phrases, "Onside kick, touchback," and save them for impressing our family and friends during the upcoming Superbowl party.
