Not entirely the case: the 2017-18 roster included Mark Smith, whom Brad Underwood recruited to Illinois. There have been issues with roster decisions in other years too, (Alan Griffin, Tevian Jones, Samba Kane). Character issues on last year's Illini team were very concerning along with issues in previous years for me means that, despite the fact that we have had a LOT of great, great people on Underwood's squads, I will continue to be wary of character issues.
Why be so sceptical? Because for a coach, it is really, really hard to look past talent, size and skill and think about (nagging) character concerns when your roster is in desperate need of something like a PG, a rim protector, a scorer.
That's realism.
