Playoff histories: Mount Union is in the playoffs for the 30th time and for the 27th year in a row. It has a 100-19 record in playoff games en route to making 20 appearances in the national championship game and winning an unprecedented 13 national championships. Centre College is in the playoffs for the third time and has a 2-2 record, failing to advance past the second round.

About Centre College: Located in Danville, Ky., the Praying Colonels are co-champions of the Southern Athletic Association and are riding a seven-game winning streak. The status of quarterback Tanner Young is in question after the SAA offensive player of the year suffered a leg injury in last week’s win over Washington & Jefferson and was replaced by John Walton, who went on to complete 12-of-17 passes for 189 yards and two touchdowns. The Colonels are averaging 42.55 points, and allowing 17.82.

About Mount Union: The Purple Raiders bring a nation-best 26-game winning streak into Round Two. They also have quarterback issues with the status of D’Angelo Fulford’s injured ankle up in the air. Kehres used three backups last week, and freshman Kyle Moore, sophomore Jake Keeney and junior Ernie Burkes have combined to complete 35-of-57 passes for 492 yards and six touchdowns. The defense, led by a stone-cold linebacking crew of Trey Williams, Danny Robinson and Mitch O’Hara and defensive back Louis Berry, has given up 12 touchdowns while scoring a nation-leading 12. The Raiders are scoring 54.5 points a game and surrendering 8.7.

What to watch: How will the quarterback situations on both teams play out? That could be the over-riding factor. Mount has many playmakers on both sides of the ball, and its offensive line will have a size advantage over Centre’s defensive front.
