There are 2 types of penalties. Running into the kicker and roughing the kicker. Running into is only a 5 yard penalty. Roughing is 15 and automatic 1st. Not sure I agree with the running into the kicker call though.
I kinda like them. Its dumb they have to walk all the way down the field each time. But each team has the same chance to win, the coin toss doesn't mean anything.
