The San Francisco 49ers have been installed as small Super Bowl favorites over the Kansas City Chiefs, but the point spread dropped quickly Sunday at sportsbooks around the nation.
The 49ers opened as 2.5-point favorites at ESPN BET, but the line dipped to -1.5 within 20 minutes of being posted and was as low as -1 at some sportsbooks Sunday night.
If the line holds, quarterback Patrick Mahomes and the Chiefs will be underdogs in a third straight game. Kansas City is 9-3 outright as an underdog in Mahomes' starts.
The Chiefs entered the playoffs at 10-1 to win the Super Bowl, their longest odds of the season. But Mahomes led another postseason run, pulling upsets over the Buffalo Bills and Baltimore Ravens to get the Chiefs back in the Super Bowl for the fourth time in the past five seasons.
