A Chicago Tribune article about Illinois' additions and subtractions from anonymous D1 coaches. Less than glowing feedback on Tilmon:
Tilmon: A blessing for Brad (that he decommitted). Could be a bust. Kept getting kicked out of games. Illinois took a PR hit (losing him), but it's the best thing for them. Sounded great to the fan base when he committed, a (potential) job-saver for John (Groce). But he has a ton of issues. Didn't even have a great senior year. He will not walk in and set the world on fire.
