This game, like so many playoff games, was won in the trenches and in the turnover battle.
The Chiefs did a good job limiting Saquon and they were good on 3rd & 4th down (Philly was 3/12 on 3rd down and 0/1 on 4th down). But, they lost the turnover battle 3 to 1 and the Time of Possession battle 36:58-23:02.
The Chiefs only gave up one long, sustained TD drive. And that was the start of the game.
After that, it was the 2 play, 14 yard drive after the INT late in the 2nd quarter and the 1 play 46 yard drive with the big pass play to Smith.
The Eagles had 3 long, time consuming drives that stalled out and ended in FGs. Those three drives had over 16 minutes in time of possession.
I think it was crazy how dominant the Eagles defense was. The fact that this game was 40-6 with 5 minutes to go is insane.
