It’s always viewed as big news when a quarterback commits to Oklahoma State, just like it is when one leaves.
Brendan Costello will transfer away from the program after a year, according to Yahoo Sports’ Pete Thamel. Costello entered OSU as a three-star recruit from San Clemente, California, as part of OSU’s 2019 class. He was the fifth-highest signee for OSU in the cycle, behind Grayson Boomer, Deondrick Glass, Langston Anderson and Trace Ford.
He redshirted in 2019, spending time on the depth chart behind Spencer Sanders, Dru Brown and even walk-on Shaun Taylor. Not much was said of Costello in the fall, but he seemed to be doing well in at least parts of spring ball last year as an early enrollee.
