Chargers...20 Chiefs...19

This wasn’t about changing defensive coordinators in midseason. It was about making a play that quite possibly saved the San Diego Chargers’ season.

Burned by a pass interference call and then a touchdown catch by star tight end Tony Gonzalez, strong safety Clinton Hart swatted away Tyler Thigpen’s two-point conversion pass intended for Gonzalez with 23 seconds left to preserve the Chargers’ 20-19 win over the lowly but scrappy Kansas City Chiefs.

San Diego’s defense played so erratically in the season’s first half that defensive coordinator Ted Cottrell was fired and replaced by inside linebackers coach Ron Rivera.

Despite coming off a week off, the Chargers (4-5) looked lethargic in the first half and were booed heading to the locker room trailing, 13-6.

Philip Rivers rallied them with two touchdown passes late in the game, then Hart saved them.

Quoteworthy: “We understand that, hey, if we don’t get this going, it might be more than just D-coordinator changes,” Clinton Hart, Chargers strong safety.
