4) Ken Whisenhunt and Gus Bradley, Los Angeles Chargers: The Bolts' late-season success was sparked by the offense and defense finding their rhythm down the stretch. The team reeled off six wins over the final seven games. The Chargers looked like a team no one would want to face in the postseason. Part of the team's success can be attributed to Whisenhunt's ability to design a high-powered offense around his veteran quarterback, Philip Rivers. The old-school play caller will set up "shots" (deep balls) for his quarterback off play-action while also scripting in some high percentage "layups" (short passes) to help the offense stay in rhythm. In addition, Whisenhunt will "feed the pig" to make sure his top offensive weapon (Keenan Allen) has enough touches to impact the game. He used this tactic to help Larry Fitzgerald play at an MVP level during a surprising Super Bowl run with the Arizona Cardinals in 2008. He dusted off that script to unleash Allen as a dynamic playmaker in 2017. With Melvin Gordon also finding his way as a runner under Whisenhunt's direction, the wily offensive architect certainly knows how to build an explosive offense that maintains enough balance to handle the physical defenses in the AFC. On the defensive side of the ball, Bradley keeps it simple so that his players can "hustle and flow" to the ball without hesitation. Pass rushers are the key to the unit's success and his creative deployment of Joey Bosa and Melvin Ingram creates chaos at the line of scrimmage. With his simple designs creating consistent pressure off the edges, Bradley sets the table for Casey Hayward and Co. to squat on routes and feast on tips and overthrows in the backend. The perfectly coordinated pass rush and coverage is a thing of beauty to watch, which is a testament to Bradley's attention to detail as a teacher. Given the presence of top-notch coordinators on both sides of the ball, the Chargers should be considered legitimate Super Bowl contenders this season.
