I was glancing at schedules and who some "top teams" have played... nobody really has played a stellar schedule yet.
Total wins by the teams they've faced:
Falcons = 4 (2 of 2 wins vs Miami & Carolina)
Ravens = 5 (2 of 3 wins vs KC and CLE)
Denver = 6 (2 of 4 wins vs Oak and CLE)
Patriots = 9 wins (2 of 3 wins vs Bills and Falcons)
Each of those teams has had 2 wins vs teams considered to be spare...
The Jets (I think have played the toughest schedule with 8 wins total), but 1 win was vs TN. The Bills have only defeated the Bucs, but they've also played the Pats, Saints.
What does all this mean? I really dunno...
... only wanted to point out that Denver isn't alone with the soft looking schedule through 4 games.
