The National Championship will take place in Indianapolis, where Lucas Oil Stadium opened for play in 2008.
Oddsmakers have often set a total points number well above where Indianapolis Colts games finish. The under in Colts home games since 2008 has been a 59% winner.
The original FieldTurf installed in 2008 was replaced in 2018 with Shaw Sports Momentum Pro, a fiber synthetic turf designed to limit injuries and hold up for 20 years. Even with the installation of the synthetic field, Colts home games have gone under the total at a winning rate since the 2018 season.
Luckily, the roof will be closed for the National Championship, providing no issues of wind or precipitation for players.
The field is maintained indoors, unlike the playing surface for the Fiesta Bowl that caused issues for the semifinal game between Ohio State and Clemson.
Considering this is the venue that houses the 40-yard dash for the NFL Combine, the surface will play fast for each team's skill positions.
