The 2021 NFL season featured unprecedented parity and a record number of walk-offs. This weekend was more of the same — and then some.
Why it matters: For the first time in NFL history, all four Divisional Round games ended in walk-off fashion. It was, quite simply, the greatest playoff weekend ever.

Chiefs 42, Bills 36 (OT): An instant classic. We may never see a better game. Patrick Mahomes (33/44, 378 yds, 3 TD; rush TD) and Josh Allen (27/37, 329 yds, 4 TD) were phenomenal, combining for 25 points in the last two minutes and overtime alone.
