Responding to sideline / bleacher chatter

[NorCalRef12]

Agreed, you really just need to relax and go through your progression. Watch your key at the snap, follow your responsibilities during the play and if you see a foul committed that needs to be penalized, throw the flag.

If you're only in your second year, everything is still probably happening very quickly. As you gain more experience, the game will slow down and you will barely even hear the coaches and fans.
