Or KC scores 5 TDs these "if and then" answers are plain nonsense , in actual reality KC came out that 2nd half and out played that defense period. (Here comes 38 more answers from Brit on how the Philly defense didn't really lose in the SB lol)
Now we really are getting into alternate reality and "if and then" answers.
There's nothing the defense could do about the scoop and score. There's no alternative drive there where they may have scored anyway.
So let's take the punt return. Let's say there's no big return and the Chiefs and Toney is downed at the 35. Even if the Chiefs score on that drive anyway it's going to take them 4:30 to 5 minutes like their previous 2 scores to do so. Which is their whole final field goal winning drive up in smoke (which started at 5:15).
Now, the Eagles defense was not great in the 2nd half and yes they were outplayed, but that return changed the complexion of the game. As did the scoop and score in the 1st half. Those are just facts.
There were a multitude of reasons the Eagles lost. The fumble, the punt return, awful run game and also in there somewhere a below average defensive performance in the 2nd half.
