I have to throw the Los Angeles Rams into the mix. With the addition of Matthew Stafford at quarterback, their offense is looking dangerous, and their defense has been one of the best in the league in recent years.
I think the Seattle Seahawks could surprise people this year. They have a great quarterback in Russell Wilson and a solid group of receivers. If their defense can step up, they could definitely make a run for the Super Bowl.
While I agree that the Chiefs and Buccaneers are top contenders, I think people are overlooking the Buffalo Bills. Josh Allen has really come into his own as a quarterback and their defense is one of the best in the league.
