Like any NFL team's chance at a playoff run, win-loss predictions can fall apart with one injury, especially at quarterback.
Before the 2019 campaign started, Indianapolis Colts quarterback Andrew Luck retired. Pittsburgh's Ben Roethlisberger, New Orleans' Drew Brees and Carolina's Cam Newton have all since suffered injuries that will change their franchise's trajectory.
Two weeks into the season, we're also prone to overreactions—prematurely crowning MVP candidates and Super Bowl contenders.
Remember, the Tampa Bay Buccaneers, Cincinnati Bengals, Miami Dolphins, Jacksonville Jaguars and Denver Broncos all went 2-0 to start 2018, but none of them finished the season with more than seven wins.
