No NFL team remains undefeated after eight weeks, with the Kansas City Chiefs' 7-1 record solidified by their narrow 27-20 home loss to the Raiders ending the league's last perfect streak at 7-0. Top contenders like the 6-1 Detroit Lions and 5-2 Buffalo Bills face gauntlet schedules ahead—divisional rivalries, late-season playoff pushes, and road tests against elite defenses—compounded by mounting injuries such as Lions DE Aidan Hutchinson's season-ending Achilles tear and widespread offensive line attrition across contenders. With nine-plus games left in the 17-game grind, historical rarity (no perfect season since the 1972 Dolphins in a shorter era) and inevitable fatigue reinforce trader consensus at 92.5% for no undefeated regular season.
