The old “three strikes and you’re out” saying can be used in many circumstances, but it certainly applies to coaching in the National Football League.
New England Patriots offensive coordinator Josh McDaniels left the organization after the 2008 season and took the Denver Broncos’ head coaching job. He lasted just two-and-a-half seasons in Denver after posting a 15-29 record (and selecting Tim Tebow in the first round of the 2009 draft).
McDaniels made a quick pitstop in St. Louis in 2011 before returning to New England as the team's offensive coordinator; a position which he has held ever since.
