Purdue Appleby was redshirted as a true freshman in 2012. In 2013, he appeared in one game as a reserve. In 2014, Purdue had a quarterback position battle in fall practice, this time between Appleby,
Danny Etling, and true freshman
David Blough. Appleby pushed hard for the starting spot over the entrenched Etling, but fell just short and was named the backup on August 18. Etling would lead Purdue to a 2–3 record of the first five games of the season, before
Darrell Hazell turned to Appleby to start Purdue's 6th game against
Illinois. Appleby led Purdue to a 38–27 victory, Hazell's first Big Ten Conference victory. On August 25, 2015, head coach Darrell Hazell named Appleby the starting quarterback for the opening game of the 2015 season. On September 22, 2015, it was announced that Appleby will be replaced as the starting quarterback in favor of redshirt freshman, David Blough. Appleby returned to his starting role when Blough was injured during the November 21, game at
Iowa. Following the conclusion of the season, Appleby was given his release to explore transfer options as a graduate student.
Florida On January 4, 2016, Appleby announced his decision to play his final year of college football at the
University of Florida as a graduate transfer. Under head coach
Jim McElwain, Appleby competed with
Luke Del Rio for the starting quarterback position, and lost out to Del Rio. After an injury early in the season to Del Rio, Appleby started seven games for the Gators in the 2016 season. Despite finishing with a 4–3 record as a starter, Appleby helped lead Florida to an SEC East title and a berth in the
2016 SEC Championship Game. In the
2017 Outback Bowl and his last game as a Gator, Appleby passed for 222 yards in a 30–3 defeat of the Iowa Hawkeyes.
