15. Pat Shurmur:
You could argue that the jury is technically still out on Shurmur as an NFL head coach. In a sense, it is, as he’s the head coach of the failing New York Giants. But most are wondering how long that will be the case, as Shurmur’s overall record is simply atrocious. He was hired as the Cleveland Browns head coach in 2011. There, he helped continue the miserable legacy of that franchise with a 9-23 record in two years. Shurmur became the Philadelphia Eagles offensive coordinator.

He later filled in for Chip Kelly as interim head coach when Kelly was fired in 2015. Shurmur moved on to the Minnesota Vikings in 2016, eventually getting promoted to offensive coordinator. He spearheaded their magical 2017 by coaching prior journeyman Case Keenum to his best-ever season. That earned him another shot at a head-coaching job with the Giants. But he led them to a 5-11 mark in 2018 and the team sits at 2-9 in 2019. Shurmur’s overall head-coaching record is 17-43, making him one of the worst head coaches in NFL history.
