The San Francisco 49ers and Philadelphia Eagles appear to be the teams to beat through five weeks.
Peter King of NBC Sports released his weekly NFL Power Rankings Monday following most of Week 5's action, and the two undefeated juggernauts sit atop of the list.
San Francisco solidified a claim in the top spot following a dominant 42-10 victory over the Dallas Cowboys. Dallas previously featured as the top team in an earlier King power ranking, so the dominant victory really put San Francisco on a pedestal in his eyes.
"Not much doubt they deserve this spot after Sunday night," King wrote.
