Shanahan took advantage of nearly every second to teach Garoppolo the offense – including all 25 seconds when radio communication was allowed into the ear piece embedded in Garoppolo's helmet before every offensive snap.
Shanahan’s voice was in Garoppolo’s ear up to the point when the sideline-to-quarterback communication is cut off with 15 seconds remaining on the play clock. It was common for Shanahan to explain the play call, the reads and the defensive look to Garoppolo in the allotted time.
“If you can get to the line of scrimmage quick enough and you can talk to him, especially the situation Jimmy was in last year, where he needed as much as you could because of his lack of time in our offense,” Shanahan said at the NFL owners meeting this week in Orlando, Florida. “Yes, we did that a lot with Jimmy.
But it’s done with all quarterbacks.“We’ve been doing that for a long time. That’s why we go no-huddle sometimes, so we can get to the line of scrimmage and you can see stuff and you can talk until 15 seconds. We’ve been doing that for a number of years.”
