He later told Scout's Gabe Brooks that it was the way Cowboys wide receivers coach Kasey Dunn and head coach Mike Gundy spoke of how they would use him that convinced him to commit.
"I just feel like how (Oklahoma State) fit me offense-wise. I'm gonna be an impact player," Alexander said to Brooks back in early May. "I like the atmosphere and the coaches' philosophy, and how everything works and how they operate their system.
"I listen to (head) coach (Mike) Gundy. I talk to him on the regular. And coach (Kasey) Dunn, the receivers coach," Alexander said. "They came and saw me in the last two weeks for spring ball, and they came and watched me at a track meet."
Fast forward to Sunday afternoon and the 6-1, 170-pound Alexander returned a text asking if the unsubstantiated report from Saturday evening was true.
"Yes, I have de-committed and opened up my recruiting," Alexander sent in a text to me. "OSU is still an option and I just felt different after I committed and wanted to re-open to make sure I made the right decision."
Prior to his pledge to Oklahoma State, Alexander had a lot of offers including Arkansas, Baylor, OU, TCU, Texas Tech, and West Virginia.
Alexander's de-commitment leaves the Cowboys with 10 commitments and now just one, Jenks' Dillon Stoner, at wide receiver.
