Perhaps the previous schools have better bigs, and he wants playing time??
It's way more interesting.
According to reports, a UCF assistant coach shopped himself and former 5* center Moustapha Thiam as a package, demanding a two-year guaranteed salary, above market for an assistant. Most passed, Cincinnati ended up with the center and asst coach.
This happened in mid to late April.
Arrinten Page had bided his time playing behind a last-year center who statistically was the same Page, but had more familiarity with the coach. Page was due to start in '25 - '26. Suddenly, he's back on the bench, filling in at best 8-10 mins. a game.
So he jumped. I believe to a far better situation for Mr. Page and his family. He's with a staff that has deep experience developing bigs. He's on a roster where he's the undisputed starting center. And he gets to display his skills in the Big Ten.
Justifiable, defensible, smart move.
