Although Coache may not be putting it too well, I get his point.
You have to set standards when your a leader. Show what "good" looks like.
You couldn't have a Sergeant - Major in the army with dirty boots and buttons undone.
The coaching staff must set high standards. However, if the coach is a big belly man, you can't not hire him because he big like Volney. As long as he is neat in appearance and sharp in thinking, his XXXXL underwear isn't an issue.
