No, during his redshirt year. There was real debate within the program about taking off his redshirt for the Illinois game to play as a true freshman after Trevor got hurt against Purdue because Thorson was showing a lot of promise in practice. The question was whether getting one game (potentially two as a W against Illinois could/would have earned a bowl game) as a true freshman was worth losing a full season from a presumed multi-year starter as a fifth-year senior. The decision was ultimately made that the benefits didn't outweigh the costs, which resulted in Oliver starting against Illinois in what turned out to be a debacle.
And, again, I don't have to show you proof because I know for a fact that this was a real discussion/decision that took place within the program.
Turk has difficulty understanding the truth and who really knows the truth in these situations.
