That team was not what they seemed, as I showed time and again that year. They may have won the title game, but they're a lousy example for "best". Winning does not denote best, it means you simply scored one more point than the other team. You get into a logical fallacy if you try to equate the two.
That said, any two teams are not as far a part as generally viewed. It's more middle with a few outliers in each direction.
All of that is another great example of why thinking that we are so terribly far from competing for the conference championship is terribly flawed.
They won the east. We beat them. That's all we'd have to do to win the B1G.
And spare me the logical fallacy mumbo jumbo. "Best" is a subjective term. If someone else was overall a better team, they would have won the division. They had the "best" conference season of anyone in the East that year. That's what actually matters.
