Bridgewater also has an audible system at his disposal, with the same goal as every good NFL system: stay out of bad plays. If the play Watson has called has little chance of success against a particular defense, Bridgewater can change the play entirely at the line of scrimmage.
Finally, Bridgewater redirects the offensive line protections by either identifying the middle linebacker in man-to-man protections, or directing the slide one way or the other in zone.
You’d be hard-pressed to find many, if any, college quarterbacks that are asked to do that much, especially at 21 years old and in a completely full-field read progression system. Most of the recent top drafted quarterbacks, like E.J. Manuel, Geno Smith and Robert Griffin III, came from systems that called for quarterbacks to only read half or a quarter of the field. Bridgewater has the ability to direct the ball to any part of the field on every snap.
