Yeah, the bolded part doesn't compute for me, either. You don't get to just magically create equality between (assumption alert!) a college kid smoking weed and an actual violent crime by saying "but this was the second time!" C'mon.
While we do not know what happened to Tevian and under what circumstances (I personally feel it is neither fair to the student-athlete nor UI to speculate of drug use or other offense), on the general discussion, I still feel it is apple and oranges. On the cases that we do know of other legal implications, it may have been the case that the penalties were too lenient rather than drug policy being too strict (yet much softer than NCAA). In the case of Black, for example, I thought the penalty was too lenient. I thought the same for Darius Paul and the decision to welcome him back.
Similarly. while our own implemented drug program may be softer than the NCAA (for obvious reasons), I have not seen much evidence that the UI drug program is stricter than the majority of other B1G programs. Heck, I have not even seen a link that details UI's own drug testing program for student-athletes, frequency, penalties, education, etc., let alone compare it to our peers. Where is it?
