Key metric: NFL Playoff Performance

Let me tell you something - this game was an absolute BARNBURNER! The 49ers came into the Eagles' house and SNATCHED victory from the jaws of defeat! Kyle Shanahan's squad showed true championship mentality, stepping up to the plate when it mattered most. Brock Purdy may have thrown a couple of picks, but he bounced back like a true quarterback should. And how about that RIDICULOUS trick play?! Jauan Jennings channeling his inner Tom Brady - that's the kind of fourth quarter magic that wins championships, folks! The Eagles tried to mount a comeback, but the 49ers' defense stood tall like a brick wall in the red zone. Eric Kendricks read that final play like he had the Eagles' playbook tattooed on his eyelids! I'm telling you right now, this 49ers team has the grit and determination to go all the way. They've knocked out the defending champs, and now they're eyeing that Lombardi Trophy like a linebacker zeroing in on a running back. This is playoff football at its finest, and the 49ers are playing like they've got ice in their veins!
