Mostly when playoff teams say nobody believed in them, it's nonsense.
For the Pittsburgh Steelers this week, they might be right.
The Steelers opened as a 13-point underdog at the Kansas City Chiefs, and that has gone down to 12.5 at BetMGM. That's still the biggest spread in wild-card weekend history, and by a decent margin.
The largest spread for a wild-card game in NFL history before Steelers-Chiefs is either 11 or 11.5 (because competing sportsbooks have different spreads sometimes, the records can vary). The history for the double-digit underdogs in this round isn't too good.
