One dominant quarter against Dallas proved to be enough for the San Francisco 49ers to head into their bye week on a high note. Brock Purdy bounced back from a shaky first half to lead three touchdown drives in the third quarter and the Niners narrowly avoided another fourth-quarter collapse with a late defensive stand that sealed a 30-24 victory Sunday night.

Yes, this is a must-win game for San Francisco — you don’t get to lose back-to-back games twice in the first half of the season and continue to fancy yourself a Super Bowl contender, much less a favorite (as the Niners recently were). You don’t get to lose to these Cowboys — my goodness, are they awful — and pretend you’re any good yourself.
