The San Diego Chargers announced that Nick Sirianni is their new quarterbacks coach. In 2013, he was the Chargers’ the offensive quality control coach, so Sirianni assumes Frank Reich’s former duties of working closely with Philip Rivers.

Sirianni started his NFL career in 2009 with Todd Haley’s Kansas City Chiefs as their offensive quality control coach, and then moved up to wide receivers in 2012. In 2010, he and Haley were credited for Matt Cassel’s incredible second year of starting with the Chiefs, helping them leapfrog the Chargers and the Tim Tebow-led Denver Broncos into the playoffs. Cassel’s stat line with Sirianni and Haley: 3116 yards, 58.6 percent completion, 27 touchdowns (career-high), seven interceptions.

After Haley’s ousting, Sirianni stayed with Romeo Crennel for one more year. It was then that Sirianni was moved to the wide receivers coach position. In that capacity, there isn’t much statistical evidence from 2012 displaying his effectiveness. Dwayne Bowe, their leading receiver, only pulled in 59 receptions, 801 yards and three touchdowns, and those numbers weren’t career-highs compared to 2010-2011.

The promotion for Sirianni is another move geared towards familiarity. Since Haley was Ken Whisenhunt’s offensive coordinator with the Arizona Cardinals during their Super Bowl run, Sirianni is somewhat familiar with Whisenhunt’s system in San Diego. It helped Sirianni’s cause that his name was being tossed around in 2010 for Kansas City’s vacant quarterbacks coach position before Jim Zorn was hired.

With Mike McCoy, Reich and Sirianni in charge of the spotlight players on offense, I suspect that the Chargers are going to keep Rivers and the offense competitive within the AFC West.
