dude they've lost ONE game all year...I somehow doubt they just melt the hell down like this
to the OP's point, it wouldn't be a meltdown. They barely took Oakland, Carolina and should have lost that game against Arizona. If they don't get the bounces going their way, they are 6-4. Not to mention they beat Denver before Manning and company got into a rhythm (that is not the same Broncos team we see today).
It takes lucky breaks to get to 9-1, but it's not out of the question to think they will stop getting the good side of bounces and start dropping close games.
On a side note, are division titles based solely on overall record or strictly division record?
