What do the San Diego Chargers, Kansas City Chiefs, Arizona Cardinals and Chicago Bears have in common? They all hired new coaches in the past month, and none of them was named Chip Kelly. And in a bizarre twist to the 2013 NFL schedule, all four teams travel to Philadelphia to take on Chip Kelly's Eagles.

Network directors will have cameras trained on each opposing G.M. while Kelly's offense has the ball, looking for those incredibly depressed facial expressions.

We can't make a fair assessment of a new coach from watching one game or even one season, but those head-to-head match-ups will definitely provide plenty of late-night cheesesteak talk about which hire was the right one, and which likely wasn't.
