Teams with questionable QB situations entering the season make up four of the top five teams in SB Nation's Week 4 Power Rankings.
At the top of the list are the Denver Broncos who lost both Peyton Manning (retirement) and Brock Osweiller (Texans) this offseason and started rookie QB Trevor Siemian in Weeks 1-4. With Siemian's Week 5 status in doubt, fellow rookie Paxton Lynch might get the nod. The Patriots (Jimmy Garappolo/Jacoby Brissett), Vikings (Sam Brandford), and Eagles (Carson Wentz) make up the other three top five teams who had QB issues leading into the season.
