It’s hard to blame him. The sophomore is currently stuck behind both Trevor Knight and Blake Bell on the depth chart and, with Knight having three years of eligibility left, Thompson was unlikely to get much playing time in the next season or two.
Thompson attempted 13 passes this past fall and completed four of them for 64 yards with one touchdown and one interception. He also rushed for 20 yards on four carries.
Since he’s graduating this spring, he should be able to play immediately next fall under the graduate transfer rule. Otherwise, he’ll have to either sit out one year or move to the FCS level.
Despite Thompson’s departure, OU should be fine depth-wise next season. They’ll have redshirt freshman Cody Thomas behind Knight and Bell, as well as true freshman Justice Hansen.
