I hold my breath each time.
A kneel down at the end of the game is the privilege of the winning team.
I do think these changes would make the game more exciting but I also feel like they are unnecessary and I disagree that the NFL should make those changes. Finally, there is no way in heck the NFL would ever do it... Want to make the game more exciting? Work on the quality of the refs and instant replay. That should be the sole focus... That it isn't makes me question the integrity of the league.
