This is the football version of a book called The Golfing Machine by Homer Kelly. Supposedly it is just chock with verbose, jargon-laded physics vis-a-vis the golf swing. Ben Hogan proteges swear by it, but it's not in print and used versions are exceptionally hard to come by.
A great shot is when you pull it off. A smart shot is when you don't have the guts to try.
