I wanted him replaced too. To me, this just doesn't change anything and doesn't sway my opinion either way. I don't think it's that relevant and I still do not see a B- grade as a major concern in any way. I'm not saying it doesn't have any meaning, just not a significant meaning when it comes to how I feel about him. If you feel like it enhances your opinion more that's ok too. We all have opinions.
I think it could be construed as more meaningful if a fan is a solid MLF backer. Then I could see it as a minor concern. But again, I just don't know how much weight I can really assign to it.
I think about it kind of in terms of, hypothetically, what if a coach is a great coach but a bit of a jerk, or even a lot of a jerk. Like a Bobby Knight though I would say without the actual physical abuse that he did because I just don't think things like that are as likely to happen anymore and if it did it would probably come out in the press. A player could assign a lower grade to a guy just because he doesn't vibe with him, it doesn't inherently mean he's bad at being a coach. There are so many variables that might lead to a guy not giving a coach an A and we're quite literally quibbling here over the difference of MLF getting an A or a B.
Ben Johnson was a first year head coach and he got one of the highest grades, how impressive is that actually? I'm not doubting his reputation but I would say it's fair to assume there's a bit of a honeymoon shine to him. MLF has been with the Packers 7 years, the stale message thing becomes kind of real after several seasons. It's hard to say if it's vets that still back him and newer guys that are less sold or the other way around. The Packers tend to the younger side of things. It's just hard to nail down what it is they might think is lacking.
I just place more importance on the things we actually see occur during football games, not the attempt to decipher the meaning of a letter grade without the deeper context behind an employee's reasons for assigning that grade to their boss.
