The coaching matchup for Super Bowl 57 between the Chiefs and Eagles is a popular topic of conversation with Nick Sirianni facing off against Andy Reid on Sunday night.
Because there is a week off between the Conference Championship Games and the Super Bowl, a popular Reid narrative is also being discussed among NFL bettors.
Reid has long been known as an elite coach — in terms of against-the-spread (ATS) performance — when given extra time to prepare following a bye week.
However, is there actual data to support this theory?
And what about Philadelphia's Sirianni with additional time to gameplan for his team's next opponent?
With the help of our Bet Labs software, let's examine ATS records for both Super Bowl coaches coming off a bye.
Super Bowl Coaching Trends
Our NFL database "only" goes back to the start of the 2003 season, so the data does not include Reid's first four seasons as a head coach, but over the past 20 season, he has been profitable off a bye.
Over that sample, Reid has amassed an 18-14 ATS record, for a 56.3% win rate when combining both regular and postseason games.
While the volume of games certainly helps, the 3.06 units earned for bettors across the games puts him third among NFL coaches, trailing only Mike McCarthy (+7.44 units) and Bill Belichick (+7.3 units).
Sirianni has a much smaller sample of games off a bye, producing a 2-1 ATS record so far in his early head coaching career.
According to live Super Bowl odds, the Eagles are 1.5-point favorites against the Chiefs, with the over/under sitting between 50.5 and 51, depending on the sportsbook.
