The decision to move on from Jim Bob Cooter at offensive coordinator seemed inevitable, but the actual transition did not happen until the 2019 offseason. In his place will be Darrell Bevell, a coach with a solid resume and a clear reputation preceding him in terms of play-calling style and tendencies.
Of course, every roster and every situation is a little different. The Vikings and Seahawks rosters he managed were not quite the same as this current Lions squad, regardless of how you feel about Russell Wilson compared to Matthew Stafford.
