Don't ever quit on a family member who is an alcoholic etc. Doesn't mean you should enable them....but never quit on them.
I haven't gone 'absolute' on Marrone. I've said I would have been 'fine' with him as the coach next year. I've also said I've no problem with him quitting. I just don't like (based on everything we've heard/read) how he left. I've said he owes the players (not me) more than that. I'm not the least bit unsettled about the potential struggles of our next coach. Every Sunday, I'm convinced the Bills will win. That's a separate issue/disease.
I've no problem with your original question. I addressed that above. In your third paragraph of the OP, you proposed he quit because of the media treatment. I don't believe that. If true, I doubt Doug was 'the guy' to lead us to the top anyway. Why would I eat crow about this?? Win or lose next year.....I won't. Your whole argument is that he was driven out and the Pegula's are forced to pick a new coach. Hence, those who 'drove' Doug away may 'get what they wished for.' It's not accurate in my eyes. He left. His choice.
I'll say this.....I'll gladly eat some crow when Doug issues an apology to his players (again...not because he quit but how). But, that's it. If we suck next year, it's not purely because Doug left. To believe that would be..... absolutist thinking. Too bad we won't ever know how Doug would have done.
