If Sunday's game against the San Francisco 49ers was supposed to be a measuring stick for the Dallas Cowboys, then the gap between the two team is ginormous.

The 49ers pinned a 42-10 loss on the Cowboys at Levi's Stadium that left the locker room as silent as it was last January, when San Francisco ended Dallas' season in the divisional round of the playoffs.

"Didn't see it coming," quarterback Dak Prescott said. "Put everything into it and got punched in the mouth. Called it a couple weeks ago 'humbling' against Arizona, but this may be the most humbling I've ever been a part of. Felt good about the preparation and felt good about everything, honestly, coming into this game, matchups, and they beat us in every aspect."
