A few questions

[New AZ Ref]

As a second year official, I have started White Hatting a few Jr. High games. Usually, I work with at least 1 senior official to have someone to talk over issues with, last night I only had 2 1st year officials.

I have a couple of questions about plays that happened last night.

1. 4th Down punt play. The snap is low and the punter picks up the ball takes 2 side steps and punts. He is knocked over by a defensive player. The coach wanted roughing, I felt he had moved into the path of the defensive player. Did the 2 side steps make him a runner?

2. Pass Play. B1 intercepts the ball at B's 40. On the run back, B2 blocks in the back at the 50 and A1 Face masks on the tackle. In this case the defense got the ball with "clean hands". I know on a regular play, the off-setting penalties and replay the down, but I think it is different on a change of possession.

3. B is flagged for illegal participation (12 men on the field, my linesman didn't flag it before the play.) A had run for a 25 yard gain. I gave the offense the choice of the results of the play or 15 yard penalty and replay down. I think this is correct, but would like to find out for sure.

Thanks in advance for your assistance
