In orderI don't have a link, but it is my understanding that after Marsteller made a verbal commitment to PSU, he made a visit to the campus and something went sour between him and Cael. (or possibly one of the other coaches) It appeared from the posts that were made here that it was PSU that encouraged him to look somewhere else. I don't know the details, so if someone has better info, please feel free to chime in.
Penn State offered.
Marstellar made a verbal commitment.
Marstellar came for an official.
Post visit the guys on the team who hosted expressed to Cael they did not believe Marstellar would be a good fit.
Cael suggested Marstellar might find a more favorable fit at a different school.
Oklahoma State announced Marstellar would be a Cowboy.
Nobody associated with the program ever challenged the narrative that Oklahoma State had effectively flipped Marstellar.
