I was about to start a thread about the 1-4 Panthers playoff chances and came across this article that I found quite interesting:

It doesn't appear to be strictly mathematical as us, the Packers, and the Eagles are all 3-1 but with different percentages assigned to each other.
Oh, and the Panthers? 6% chance to proceed to Round 1. Super Bowl loser's jinx reborn.
