What is the division 1 record for highest average passing yards per game?

As of my last update, the NCAA Division I record for the highest average passing yards per game in a single season is held by Bailey Zappe, who achieved an average of 435.4 yards per game while playing for Western Kentucky in the 2021 season. This record reflects Zappe's impressive performance and efficiency as a quarterback throughout that season. Records may change, so it's advisable to check the latest statistics for any updates.
