Only because the offense failed on all the previous “game-deciding possessions”,And yet, there we were...we all saw the scoreboard: Rams 13 TB 9 with 48 seconds to go.
And yes, the defense failed on the one possession. That just happened to be the game-deciding possession.
Including the one immediately ahead of the one you’re referring to.
The entire game matters.
And the defense significantly outperformed the offense over 60 minutes.
