think it's a coincidence that the schedule toughened just a little and all of a sudden our ten win seasons are gone?

weird.. Pat yourself on teh back for beating upn a 10 year old, that is sentimentally what you are doing by patting BM on teh back for beating a bunch of inferior teams... When he starts having a winning record vs teams with records over.500 then we can talk about him being above average... Your premise that BM is the best we can do is absurd. you can not know that no one can.... Suppose your spouse beats you but she nice sometimes.. no need to get out of the relationship yet though because the next one might be worse? Logic Fail.

Or business world, you have a salesman who sales what any other salesman selling your product would , Your product isn't selling as much as your rivals though.. no need to replace him because the next guy MIGHT be worse? He MIGHT be better too.
