Yet another classic might be in store in the Peyton Manning-Tom Brady rivalry, the longest and best between two brilliant quarterbacks that the modern NFL has seen.
Here's an added twist: Sunday is the first game in NFL history matching quarterbacks with more than 150 regular-season wins.
Brady, now 37, is 10-5 against Manning, now 38, including 8-3 in the regular season. Brady has led the Patriots to three straight wins over Denver in the regular season, two of those with Manning at the Broncos' helm.
Both are playing lights-out recently, and Manning is tied for the longest streak in NFL history with 13 games of two or more TD passes.
"Maybe when I'm his age, I'll be playing as well as that," cracked Brady.
"That's the cold, hard facts," Manning replied.
