A few contenders fell in Week 5 of the 2023 NFL season, which has shaken up how we look at the NFL in the futures market and this week's NFL Power Rankings.
One contender that stayed perfect was the San Francisco 49ers, who dismantled the Dallas Cowboys on Sunday Night Football behind four touchdown passes from Brock Purdy. The 49ers and Philadelphia Eagles (who beat the Los Angeles Rams) remain undefeated through the first five weeks.
Dallas wasn't the only contender who lost in Week 5, as the Buffalo Bills and Baltimore Ravens dropped their games as well.
