It's always nice when someone says you dress well. It's a pleasant compliment and makes you think you're doing something right.
All of these men are doing something right, because they will most likely be leading their respective teams into battle come March Madness. That kind of pressure keeps them busy for sure, but that doesn't make it acceptable to look like a public joke. My mom always taught me to look good if I wanted to make an impression. I'm willing to bet I'd try much harder to wear a tasteful suit and tie if I knew I'd be seen by a million pairs of eyes.
