Firing a guy who has a drinking problem just makes an unemployed guy with a drinking problem. That doesn't help anyone. In fact, it is counterproductive.
Hopefully, Eichorst calls him in and tells him that he has taken his last drink and tell us what do you need from the University to get this fixed and behind you.
However, make it clear that his last drink has to be THE LAST DRINK.
While I generally feel people fly too far off the handle about DUI, if the information about # of offenses and amount of BAC on this offense are true, then I don't see why the university would take on the potential liability.
If it's because of his value as a coach, I have to question (a) whether he can be effective as a leader of players if he shows such poor judgment, (b) has any credibility on the recruiting trail, especially in the face of negative recruiting, and © whether being a full time coach in the pressure cooker that is Nebraska football is the most conducive situation for recovery and bad behavior avoidance.
If the info is accurate, I don't see how he can be kept on, for his good or the good of the program.
