Overtime

[Illini_Ref]

My state (Illinois) uses the suggested OT procedure that is in the back of the NF rules book.

I have a couple of questions. It seems that crews are doing different things in reference to the administration of the OT. First is the coin toss.

It is my understanding that the coin only gets flipped ONCE. For a second OT, the toss loser gets his choice of end of field, offense, or defense. For third and subsequent OTs, the choices are simply alternated with NO new choices. You just simply use the choices for the first OT for the third and second for a fourth OT, and so on. Am I correct? If not, someone correct me please.

Second question is in reference to choosing an end. Let's say Team A has a lights out kicker. Team B wins the toss and elects to play on the end facing the wind (north). It goes to a second OT and Team A then elects as it's first choice to play on the south end. Do you play each subsequent period on those respective ends, meaning each OT will be on opposite ends of the field. I know that the losing team of the toss can elect to go to the other end for the second OT as it is in the case examples in the book, but does it apply for all other OTs?

Thanks.
