The series: This is the 51st meeting between the two schools and Mount Union has won 46 of the 50 previous games. The Purple Raiders have won 40 consecutive games against the Cardinals with the last loss coming in 1977 (24-7).

About Otterbein: Last week’s loss to Ohio Northern suggests the Cardinals are better than the record indicates. The program is rebuilding after losing eight all-OAC performers to graduation. Offensive problems are evident as it has scored just twice in three games. Three sophomores and a freshman start on each side of the ball and as many as 15 underclassmen could see significant playing time. That group includes Medina sophomore Jacob Leonardi, who starts at wide receiver, and Medina freshman Demetrius Shannon, who starts at cornerback. Streetsboro sophomore George Redding is listed as the backup slot receiver to senior Payton Vanderkooi, who is one of just four returning starters on offense. Redding has caught 13 passes for 137 yards. The lone victory came in the season opener, 10-7 over Ohio Wesleyan.

About Mount Union: The Raiders take their nation-best 18-game winning streak on the road in the season’s first game away from Mount Union Stadium. The streak should reach 19 behind a defense that has limited opposing offenses to 10.3 points and 247 yards per game. Defensive touchdowns scored by cornerback Louis Berry, linebacker Danny Robinson, end Andrew Roesch and safety Austin White are the second most in the country in Division III. An evenly balanced offense has scored 36.3 points per game while rolling up 467 yards — 264.7 through the air and 202.3 on the ground. Look for junior quarterback D’Angelo Fulford to bounce back after an uncharacteristically jagged performance last week against John Carroll.
