Mike Zimmer has criticized his offense's play-calling twice in recent weeks. He has also praised John DeFilippo twice in that span. That math doesn't equal net zero.
Zimmer's frustration seems deeply rooted and based on fundamental differences in offensive philosophy.
The head coach desires a run-heavy approach, or at a minimum, a balanced attack. His offensive coordinator abandoned a productive running game Sunday at New England faster than Usain Bolt in the 100 meters.
Zimmer's repeated criticisms represents a pattern, which hardly makes for a harmonious operation. What remains to be seen is whether this is merely growing pains in a new relationship, or a fundamental divide that creates an unsustainable situation.
The odds don't favor a lasting partnership if Zimmer and DeFilippo don't find common ground on philosophy — and more importantly — execution of that vision on game day.
It's one thing to blow off steam after a tough loss. Zimmer's disgust following Sunday's 24-10 loss at New England felt different.
The Vikings ran the ball only 13 times compared to 44 passes. Asked if his team ran the ball enough, Zimmer was curt.
"No," he said.
