White thought he might be a professional pitcher early on in high school, as he was named a Louisville Slugger All-American as a junior (9-2, 0.43 ERA). But when he got a chance to start at quarterback for the University School in Fort Lauderdale, he led the team to a state title and was named the Florida Class 3A Player of the Year. White signed with South Florida, and got a chance to play immediately. He suited up in six games (starting five) in 2013, completing 53 percent of his passes (93-of-175) for 1,083 yards, three touchdowns, and nine interceptions. He started again in 2014, but his performance (50.4 completion percentage, 1,639 yards, eight touchdowns, seven interceptions in 10 starts) did not guarantee him a starting job for the following year. After falling behind in the depth chart in spring 2015, White decided to transfer to Western Kentucky. He redshirted in the fall of 2015 as a transfer student, sitting behind star passer Brandon Doughty. White took over the reins in 2016, and was named second-team All-Conference USA and the C-USA Newcomer of the Year after completing 67 percent of his passes (280-of-416) in the Hilltoppers' wide open system. He used that pitcher's arm to throw strikes around the yard for 4,363 yards and 37 touchdowns against a measly seven interceptions. White's numbers were not quite as impressive as a senior (completed 65.7 percent of his 560 throws for 4,177 yards, 26 touchdowns, and eight interceptions), but he played well enough to be named second-team All-Conference by league coaches.
