Almost exactly eight years ago, the Vikings introduced Mike Zimmer as their new head coach.
He was brought in to fix a team that had lost double-digit games three of the previous four seasons, with defensive lapses telling much of that story. Zimmer did that, and after his first four years he looked to be on a trajectory that could keep him here for the very long term.
But now here we are: The Vikings are starting over again after firing Zimmer and general manager Rick Spielman on Monday. And again, the defense is the thing that probably needs the most fixing.
