Because he got booted after his senior season. He only had 1 game left and the Insight Bowl isn't exactly getting all the attention. Win or lose, this game isn't changing the Big Ten standings, it isn't changing the BCS rankings, if Iowa wins Missouri drops from 12th to 20th, big deal, etc... The only thing that appeared on ESPN was when Adam Rittenberg put something about it in his blog, it wasn't front page news (other than in Iowa) of him getting arrested and kicked off. They didn't need a press conference to say he was kicked off, they needed a press conference to stop the rumors.
Now let me ask you how him getting booted hurt the program?
Are you kidding me? How did his actions hurt the team? Lets see.....
1. He did bring a conference wide spotlight to "drug use" at Iowa. The regional and national media did cover this and did report that there are multiple drug allegations with Iowa players (never mind the bit about players living in drug houses). If you aren't watching our news, thats' all you heard.
2. Recruits hear this. Their parents hear this. If your kid is looking at Iowa and Michigan or Penn State (same records), how comfortable are you going to be about sending him into a program with newsworthy drug use/abuse?
3. It hurt our bowl. People are just now talking about the bowl game again. For the last ten days or so, no one has said a word about it. Sales are down. Lots of people have said they weren't going to go and used this as the final nail in the coffin.
4. It hurts the other kids on the team who do everything right. The Iowa program is a reflection on them (and vice versa). They are all associated with this. Imagine having to go to classes and get bogged down in questions from classmates about this. Imagine people assuming you're involved because you're a football player. Imagine the phone calls from your friends and family.
5. As a parent, I had to explain to my young kids why DJK was kicked off the team. (Thank you to the other kids on the bus!) I suspect young kids aren't the only ones let down by DJK.
I could go on but I suspect you see my point.
