The Denver Broncos are off to a perfect start under quarterback Trevor Siemian. The New England Patriots also are 3-0 despite playing without superstar Tom Brady.
The past two Super Bowl winners also share the top spot in the latest AP Pro32 poll released on Tuesday.
The Patriots received six first-place votes and the Broncos earned five and both have 377 points from balloting by media members who regularly cover the NFL.
It's the second consecutive week for a tie at the top spot in the poll. Last week the Patriots and Steelers were tied at No. 1.
The Patriots will play their last game without the suspended Brady when they host the Bills on Sunday.
