If this Sunday becomes Brett Favre's last, last, really last game, I'd like to get a ticket (stub) from the game. IF anyone here is attending the game, please contact me and we'll work out a deal. I've got my stub from his first start, his TD-record game, his passing-yardage record game, and his last game in GB. I would love to get one from his final game. Heck, I'd like one from the game in NY last year where he set the interception record, too (good with the bad, you know?).
Short answer: a punter is only capable of producing so much force. This limits the amount of force on the X, Y, and Z axis. My thought is that for punts that have enough force on the Z axis to achieve a 4.
