Robertson, a junior for this upcoming season, posted this note.
"I would like to personally thank Coach Gundy, Coach Spencer, and the rest of the Oklahoma State coaching staff for giving me the opportunity to come here and get my education and play for the past two years but at this time I think it is best for me to transfer schools.
"At the end of the day my ultimate goal is still to get my degree, reach the NFL and play at a high level. I appreciate everyone I have come across in my time here from my teammates to the people over in academics and the fans that I have come across. As I start my new chapter, I ask for nothing but support. And once again, thank you Stillwater. You guys will always have a place in my heart."
Robertson, the son of two Army veterans and two athletes (father in football and mother in track and field), came to Oklahoma State from Killeen, Texas where he was a Top 100 recruit in the state of Texas. He actually played as a true freshman alongside fellow freshman, at the time, Jordan Sterns.
He played his first game at OSU in San Antonio's Alamo Dome against UTSA. He finished the season with four tackles, three unassisted. Last season he played in 11 games, mostly on special teams. He had eight tackles, seven unassisted.
It may have been a little revealing on Wednesday when we had new safeties coach Dan Hammerschmidt on the show and he mentioned most of the safeties with an emphasis on Jordan Sterns and the emerging player in the spring in Jerel Morrow. He also spoke a lot of Tre Flowers, Dylan Harding, and redshirt freshman Tre Roberts. He did not mention Robertson, but spoke of the three incoming freshmen and how good they looked in reporting.
Robertson is a good player with potential and it sounds like the emergence of Morrow this spring may have pushed him into thinking he needed to go somewhere else to find playing time.
