Why? To me looking presentable has always been part of any professional job, whether it's a sweater or suit. I absolutely hate the sweatsuit/hoodie thing and especially in college where you are always trying to influence kids, parents, coaches, etc... I think looking presentable with whatever you determine is acceptable/expected wardrobe and appearance is not hard to do. If I have an employee who isn't meeting a standard, I talk to them and I think any AD should communicate that if they have an expectation. Having said that, I've never noticed Cronin looking crappy. Easy to control. Much fairer to critique than height for instance.
I only know his suit for IU looked strange....tie too fat or something. But nothing like Archie used to look. I 100% agree that its something you'd expect an AD to mention if it was a continuing bad look. That's one of many reasons, the biggest being not holding Woodson's feet to the fire, that I don't trust Dull Son.
