When Parker Livingstone first arrived in Norman, he had a lot to learn. The Texas transfer wide receiver was expected to come in and immediately start for the Sooners as a high-impact weapon on offense. Picking up a new offense under Ben Arbuckle, learning to play with a new quarterback in John Mateer and getting to know an entire new team and program. But now eight months into being a Sooner, Livingstone feels much more at home. And it's starting to show in his play in fall camp, as he's been one of OU's best receivers so far.
