Just trying to get a feel for which is the most important, then what comes second, etc.

I'm sure after a little time this will all happen pretty quickly (and hopefully become second nature), but as a new official I want to be sure of my priorities.

CANADIAN MECHANIC:

For pre-snap fouls: With whistle in mouth already: Whistle and clock simultaneously. Throw the flag. In that order, always.

For pre-snap fouls: WithOUT whistle in mouth already: Whistle, then clock. Throw the flag. In that order, always.

The whistle first prevents other illegal action.
