FWIW, I think mostly just, how recruiting works in college has totally changed.
The portal is where you recruit now. Obviously we still get HS commitments, but it's silly at this point to expect most of your HS recruits to even be on your team for 3+ years. You can get guys that are more ready to contribute to your team right now in the portal in most cases.
I hope Fears (and Morez Johnson, and Jase Butler, and whoever else) come here and stay 4 years and end up Illini legends, but chances are 50%+ of them transfer and we replace them with guys that are ready to contribute to the team right now, instead of 2 years from now.
