I have a few issues with the new rules.
"Ball goes out of bounds = touchback."
Unless it goes out of bounds BEFORE the end zone, then it's a 20 yard penalty (like in real football) and the football is placed on the 40 yard line.
"Fieldgoals"
You should be only be allowed fieldgols if the spot of the ball is at the enemies 15 yard line or less. Also, the team should have to tell the ref that their kicking a field goal.
"onside kicks"
No, that's ridiculous. Mathematically speaking, the kicking team will get the ball 10/10 times.
"2 point conv"
Do you get a blitz?
"challenges"
How the hell are you going to challenge? Is someone recording?
