Key metric: NFL Playoff Performance

Let me tell you something - this NFL playoff action is ELECTRIC! We've got a real SLUGFEST on our hands, folks! The Bills showed true CHAMPIONSHIP MENTALITY with that clutch fourth quarter performance. Jacksonville gave it their all but Buffalo stepped up to the plate when it mattered most.

This is playoff football at its finest - no team wants to go home, and they're all leaving it ALL on the field. I'm telling you right now, buckle up because we're in for a WILD RIDE as these games come down to the wire!
