I'm usually one to say the refs are never why a team loses a game, but to not get that 4th down tush push when that was clearly a 1st down was a back breaker - that's not accounting for the Worthy "catch" that pretty clearly hit the ground.
At least when Brady was running through the league, his teams more or less deserved to be there. This just feels like the Chiefs got plot armor because if they don't play well, the refs got their backs.
There was not a flag on that play, was just a f*** up by Nantz/Romo who pretty immediately clarified.
