middling results in the playoffs yes, but good sustained success within the regular season over that time period as well outside of a few years prior to Lamar.I mean, we aren't talking about becoming the Browns and switching nearly every year. We've had middling results for about a decade, along with many less than stellar coordinators being swapped out.
And I could point to the Eagles. They moved on from a proven winner to a coach that won them a Super Bowl. Then when Pederson seemingly lost the team they moved on and are currently the top seed in the NFC.
