He is a larger part of the problem. He, not Tom Telesco, runs the football operations for the franchise.

“John Spanos was named President of Football Operations for the Chargers in May 2015 and oversees all football-related functions of the team, including player personnel, coaching, player finance and the salary cap, medical, equipment, video, player engagement and security.”

He is the flunky son of the idiot owner and pretty much oversees the entire franchise. That paragraph above is directly from the team website. John has final say on all football operations and decisions.
