1. Kansas City Chiefs

They are gunning for a third straight year of playing in the Super Bowl. Barring an injury to QB Patrick Mahomes, that seems likely.

2. Los Angeles Chargers

Justin Herbert is a legitimate franchise quarterback and they are doing everything they can to protect him going forward.

3. Las Vegas Raiders

With an extra Wild Card spot they are considered contenders for one, but there are too many questions still on defense and now the offensive line.

4. Denver Broncos

Is this team any different with Teddy Bridgewater at quarterback? We shall see in a tough division.
