Football, coaches like to say, is a game of matchups.
That's true for coaching in the NFC North, and the matchups are no longer favoring Mike Zimmer.
Zimmer is 63-46-1 as the Vikings' coach. That's an impressive record that has granted him longevity. He is the longest-tenured coach in the division. Only six NFL head coaches have held their current jobs longer than Zimmer.
Look at the matchups he's currently facing in his most important games, though, and a Vikings fan might have reason to worry.
On Sunday, the Vikings lost another almost-must-win game, this time 33-27 to the Chicago Bears at U.S. Bank Stadium.
The Vikings have lost two straight to fall to 6-8. They could theoretically make the playoffs, but would have to win at New Orleans and Detroit and then have the NFL bracket chosen by the same fools who chose the college football playoffs.
Sunday's loss means that Zimmer is 1-5 against the Bears' Matt Nagy, who just three weeks ago was thought to be coaching for his job.
Zimmer is 1-3 against Green Bay coach Matt LaFleur, another young offensive coach Zimmer seems to think of as an affront to grumpy old defensive coaches.
