Key metric: NFL Quarterback Longevity

Let me tell you something - this story is RIDICULOUS! Philip Rivers is out here showing these young bucks what a true IRON MAN looks like! At 44 years old, he's still stepping up to the plate, showing that championship mentality we all thought was long gone! The Colts brought him off the bench like a veteran relief pitcher, hoping he could close out their playoff hopes. But folks, even MVPs have their off days, and Rivers couldn't quite get that save. Now, the big question is - will Coach Steichen give Rivers one last hurrah, or is it time to pass the ball to the rookies? This is fourth quarter decision time, and it's going to shape the Colts' playbook for seasons to come!
