Strength vs. Strength

The key to this game will be what happens when the potent Western Kentucky offense faces the powerful Appalachian State defense.

Zappe absolutely aired it out this season. His 5,545 passing yards were 1,000 more than the second highest passer, Will Rogers. His 56 passing touchdowns also led the country, and were 13 more than Heisman Trophy winner Bryce Young.

Offense wasn't the issue in Western Kentucky’s four losses this season. They began the season with three losses in Weeks 2 through 4, but still scored 35, 31, and 31 points in those defeats. Considering they were against Michigan State and Indiana, those performances look far better in hindsight. Even in their conference championship loss to UTSA, Western Kentucky still scored 41 behind 577 yards and four touchdowns from Zappe.

Western Kentucky will now face a Mountaineers defense that is 17th in the nation in yards allowed per play, and sixth in opposing quarterback completion percentage. It also has a stellar 8.4% sack percentage rate and allowed just 19.3 points per game in 2021.

If Western Kentucky is going to potentially pull off the upset, Zappe will need to have one of his best performances of the year by playing up to his seasonal averages.

Western Kentucky and Appalachian State Betting Trends

  • Western Kentucky is 5-1 ATS in its last six games
  • Western Kentucky is 4-1 ATS in its last five games following an ATS loss
  • The over is 5-0 in Western Kentucky’s last five non-conference games
  • Appalachian State is 1-5 ATS in its last six games vs. Conference USA opponents
  • The over is 4-1 in Appalachian State’s last five games coming off a loss

Get ready for a Zappe attack

When two teams from different conferences meet up in the postseason, I prefer to give added weight to the stronger offense. Defense tends to have an advantage early in the season when offenses aren’t in sync or when they have familiarity with the opposing teams’ players or strategies.

By this point in the season, the offenses, especially Western Kentucky’s, are motoring along at full speed. The Hilltoppers have scored 47.2 points per game over their last five games, and Zappe is clearly in rhythm with receiver Jerreth Sterns.

Appalachian State has a very strong defense, but this is going to be the most unique offense they’ve faced all year. This program has struggled in recent years against opponents from Conference USA, and I don’t expect them to have an answer for one of the nation’s most prolific passers.
