Tom Brady's 8-yard first-quarter touchdown pass to Rob Gronkowski erased an early 3-point deficit against the Kansas City Chiefs in Super Bowl LV. The Bucs never trailed again, cruising to a 22-point win and an easy cover (+3) as the Super Bowl spread didn't come into play for the 12th straight year.
That streak was finally snapped in 2022 when the Los Angeles Rams won but didn’t cover the spread in Super Bowl LVI.
Super Bowl Spreads
In a typical season, NFL spreads come into play in approximately 20% of games, i.e., the favorite wins outright but fails to cover the spread. And through the first 45 Super Bowls, the spread mattered at a similar rate (approximately 22%); seven favorites won outright but lost against the spread, and two favorites won outright but pushed against the spread.'
Until the Rams’ 3-point win as a 4.5-point favorite last year, not since LaMarr Woodley's strip-sack of Kurt Warner in the final seconds of Super Bowl XLIII secured an outright win (but ATS) loss for the Pittsburgh Steelers (-6.5) over the Arizona Cardinals, had the Super Bowl spread come into play.'
