I think Doug’s record since he quit in Buffalo has shown that while he might not be a “bad” coach, he’s also not a particularly good one. He’s middling on his best day, with a 39-46 career record including playoffs. He brings discipline to a team but doesn’t appear to be very adept at game planning for either the offensive or defensive side of the ball. He’s had conflicts with star players and his overly conservative mindset kept his team from going to a Super Bowl. He did win a couple of playoff games so there’s that, but he also took that Jaguars team coming off an AFC Championship game appearance and drove them into the ground (11-21 since).
