Here are five things to know about Day:

1. Chargers QB Coach

Day has spent the last two seasons working on Jim Harbaugh's staff as the quarterbacks coach.

It was his second stint in Los Angeles, as he previously held the same role, and was also the Passing Game Coordinator, for the team during the 2021 and 2022 seasons.

2. Working with Herbert

Day has worked closely with the Chargers franchise quarterback during his time with the team.

Justin Herbert has achieved two Pro Bowl nods with Day as the position coach in 2021 and 2025 as well as seen some of his most efficient years with him.

During the 2024 season, Herbert led the NFL with a 0.6 interception percentage and set a career mark with a 101.7 quarterback rating in 17 games.

Not to mention, Herbert also set his career-high passing yardage seasons with Day as the quarterbacks coach when he threw for 5,014 yards in 2021 and 4,739 in 2022.

3. NFL experience

The quarterbacks coach has an extensive history coaching at the NFL level.

After getting his break as an offensive quality control coach from 2007 to 2009, Day has spent eight different stints with teams as a coach.

He's spent multiple seasons with Chicago, Washington, Miami, another stint with San Francisco and with Houston aside from his two chapters with the Chargers.

4. Work at other positions

Day has coached other positions during his career aside from the quarterback.

The coach spent two seasons as an assistant offensive line coach in Washington during the 2014 and 2015 seasons before being hired to coach tight ends with the Dolphins.

He would go on to spend three seasons at that position in Miami.

5. Start in coaching

Day began his coaching career in the high school ranks.

From 2001 to 2004, Day spent his time coaching at Auburn Riverside high school in Washington, going from wide receivers coach, quarterbacks coach and eventually offensive coordinator.

He would then go on to serve as the offensive quality control coach at the University of Michigan during the 2006 season before earning the opportunity with the 49ers.
