...watched part of the PennState "presser" following the Iowa dual- - -Cael Sanderson, being a great coach and a great wrestler, doesn't understand how to be interviewed without being condescending and mildly rude. I have seen him "come across" this way in other interviews- as if he is being bothered. If he is nervous/uncomfortable being interviewed, that is a factor that, with practice, can be overcome. If that is who/what he is, he probably is a prick and a cheap tipper in a restaurant, also.
If someone is doing their job, and the results of that job will benefit your program, you, and your line of work- be a professional...
Consider the culture Cael Sanderson grew up in. Mormon culture of "we're right and everyone else in the world is wrong" and "we are persecuted because we, and only we - have the truth".
You are seeing Cael display the attitude of church leadership. It is a learned behavior and one that you see in his culture - Utah Mormons. There it is often referred to as the "Brother Humble" syndrome. They grow up seeing it in church leadership and it carries over big time to business and personal relationships. The higher up you go the more it tends to show. Some overcome it, most in that society do not.
No matter what, the guy can coach wrestling.
