This is Whisenhunt’s second stint with the team after being their offensive coordinator in 2013, which was McCoy’s first season here. That year, they installed the quick-hitting passing attack that revitalized Philip Rivers’s career -- his best three career marks in completion percentage have all come in the last three years. Given the scheme, San Diego’s 29th-place ranking in deep pass percentage is to be expected. They signed Travis Benjamin to take over the vertical role vacated by Malcom Floyd, but Floyd’s 11% target market share is a sobering reminder that the vertical game is not what McCoy and Whisenhunt are really all about.
