Maybe it is just me because I don't usually post on here, but I am confused. It sounds as if you are trying to convice people that Marv Levy was not a good coach, and he was lucky the Bills hired him. He was lucky Bill Polian was here. He was lucky he had a talented team. I am going to put my faith in the guys that played on his team, and constantly praise his coaching ability. I am going to put my faith in his former bosses (Polian and Ralph), who have the utmost respect for what he accomplished. I am going to put my faith in the HOF voters who elected him. I wouldn't say that he was the greatest coach of all time, because that would be a stretch. I won't say he will be the greatest GM of all time, beause that would be a stretch. I will say that he will bring leadership and stability to a franchise in desperate need, and that is not a stretch.
There are many talented teams out there that do not go to the super bowl. There are teams in all professional sports that are filled with talent, but cannot translate that talent to wins. To not give any credit to Levy for the Bills greatness is ridiculous.
As for the business analogies and all of the talk about synergy, here is another. Let's take a company with the most qualified workforce (players) and one of the greatest CEO's (Polian). Now let's put manager's and director's (coaches) in place who don't belong in their role and do not empower their employee's. You tell me how long that company will last. That is what you are trying to explain was the situation.
