I wouldn't like it General.....
What I would like and think would make the game Unbelievably exciting is if they came up with a way in which one side of the ball, the offense or defense, would be outmanned due to numerous penalties, kind of like hockey. For example, it a team commits more than 3-5 penalties in one quarter, then they lose one man for so many minutes on one side of the ball. Wouldn't it be great to see if a defense could hold off an 11 man offense with only 10 guys? Or what a slap in the face it would be sometimes if we saw, the Colts for example, still drive 80 yards with only 10 guys on their offense vs. a full 11 man defense. I can guarantee you one thing. Coaches would be spending MUCH more time on the working with penalties with their teams in the offseason!
