The Detroit Lions and Kansas City Chiefs entered Week 15 as betting favorites to win the Super Bowl.
That was before Chiefs superstar quarterback Patrick Mahomes limped off the field Sunday, leaving backup Carson Wentz to finish a 21-7 victory over the Cleveland Browns.
It was also before the Lions’ injury-depleted defense lost three more players, reaching a potential breaking point in a 48-42 home defeat to the Buffalo Bills (Detroit trailed by 17 in the fourth quarter and 13 in the final minute).
