I knew someone would say that....
I guess I'm thinking for the entertainment/ competitiveness of it. I've always liked how the math of 1,2,3 or 6 points effects a game, if that makes any sense. It makes a safety worth less, a field goal worth less, and the extra point solid freaken gold. (note worth less, not worthless) I'm for change. Just make sue its for the better.
Also: can you see a game ending with the kneeling of an extra point. Or games where one team is so far ahead the kneeling off could start early. Especially if its a team locked into the playoffs already. Why risk injury and giving up a point?
