FLOWERY BRANCH, Ga. — Three months after their closing, I'd like you to think back to the Summer Olympics for a moment. Specifically, the track events.
A large number of the races I observed during those two weeks of sports bliss evolved in a similar pattern. Immediately after the gun, all of the racers were mostly bunched together and running at what appeared to be the same speed. Very quickly, though, a chunk of runners would fall behind. Then, that main cluster began to elongate and form a few little sub-groups within the larger structure.
What inevitably came next in those races I watched mirrors our current NFL moment. The rest of the group didn't sink back, but rather the superior runners began to pull away. Through eight weeks, there are only two teams in a tier of their own — and for different reasons. However, a really nice crop of teams forms the main cluster behind them. Which ones can start separating?
Here are my updated NFL power rankings after Week 8.
