They literally did stop him for most of the game?? What do you want the 49ers to have even more weapons than they already do?
I mean they picked off Mahomes at midfield in an all time stupid throw. 100% guaranteed if it were the Bills the 49ers would have scored a TD and everyone would say "that one's on Allen." Instead the Chiefs defense held them to 0 points. That's why they just won another Super Bowl.
If you're gonna give up so much free access, 100% of the time Andy Reid will just have his pass catchers run 6 yards and turn around. Over and over again. I hate that teams let them get away with it.
No player is as important as the elite QB. But I'll phrase your point like this - the difference between Chris Jones and the best defensive lineman on the Bills is the biggest difference between our teams over the past few years. If I had a choice between replacing Allen for Mahomes or replacing Oliver for Jones, it's a no-brainer.
But if both teams score the same points on their first drive, the team that received first just needs a FG to win. It's not college rules where it keeps going back and forth.
