I'm not worried about Pete's ability to coach or build winning cultures. That's a proven commodity. Don't get me wrong. The last four games and next season are absolutely pivotal for Pete's continued tenure with the team. But the current criticism is so disjointed that it's hard to take seriously. For example, some of the same people who deride Geno as a backup QB are the ones who think Pete's underachieving with a talented roster. How do you square that circle? QBs correlate with winning more than HCs.
There are genuine critiques by people who are not doing mental gymnastics to confirm their priors. And the issues they bring up are fair concerns. The team's highest-paid players are some of the least disciplined. The coaching staff, particularly on offense, doesn't always scheme in ways that benefit their personnel. Similarly, despite being above average on a down-to-down basis, the defense is horrendous because they continue to give up big plays. Those are correctable issues, but until they are corrected, it falls on Pete.
