2. Kansas City Chiefs
> Avg. odds: 6.7/1
> 2018 record: 12-4
> Strength of schedule: 5th hardest (tied)
> Key addition: Frank Clark
QB Patrick Mahomes dominated NFL defenses in his first year as a starter with the Chiefs. But his own defense will need to play better for Kansas City to win the Super Bowl. While the Chiefs’ offense scored more than any other in 2018, the defense was among the worst. To address this, KC brought in a bevy of new defensive players, including Tyrann Mathieu, Frank Clark, and Alex Okafor.
1. New England Patriots
> Avg. odds: 6.5/1
> 2018 record: 11-5
> Strength of schedule: 2nd easiest (tied)
> Key addition: Demaryius Thomas
The defending champion New England Patriots show no signs of slowing down. After Rob Gronkowski retired, the Pats reloaded with new wideout Demaryius Thomas. If those players can perform, and New England’s defense continues to excel, it may be tough to stop the Pats from repeating as Super Bowl champs.
