Going with Eagles and Chiefs mainly because that's the matchup I want to see the least and given how things have gone recently, whatever I want, the opposite happens.
If Washington does win, it's because they slow down Barkley just enough to force the Eagles to lean on Hurts, who I believe is going to be a liability if pressed to do more.
Chiefs and Bills has become Brady versus Manning in the playoffs. it's that hurdle Manning could not clear for ages until he finally did. Maybe Allen could do the same, but there's every reason to doubt it happening in the now.
