The day of reckoning has arrived.
I will say what I said before the AFC Championship game. This means far more to the opponent than the Chiefs. If the Eagles lose this having brought in Barkley, and with the disrepuatable fanbase that follow them, and having failed for the second time in 3 years, then yes it would be an outright disaster.
The Chiefs have been here 5 times already, 7 times to the AFC Championship game. No one is going to blame them for failing to get a threepeat which is simply icing on the cake. The will still have the greatest QB in the game who will almost certainly get back to the Super Bowl next year.
