Jim Schwartz
I could probably make a list dedicated exclusively to terrible Detroit Lions coaches and I still think I’d have to leave a few worthy candidates off the list. Jim Schwartz was no Rod Marinelli, but he had his fair share of lowlights. In addition to being brutal with the challenge flag, Schwartz also made an illegal challenge — for those who don’t know, throwing the challenge flag at the wrong time is an unsportsmanlike conduct penalty — that cost him a win against the Houston Texans back in 2012.
It’s also worth mentioning the brawl Schwartz started with then San Francisco 49ers coach Jim Harbaugh. Harbaugh shook his hand too hard after the game so Schwartz chased him down. It was quite the spectacle.
