I wonder if there is a chance Hamlin still goes to Prep School while being committed to Illinois for 2020. Kind of like Javon Pickett with Miznoz. This is assuming the Kouma situation gets resolved quickly.
Hamlin is not listed on the roster because he has not yet signed a financial aid tender and the program has not officially announced the addition.
If money isn't an issue for Hamlin he could enroll at UIUC and "walk-on" his freshman year. Having access to our Gym, coaching staff, and weight room could be seen as more beneficial than prep school potentially.
