Most of what we see of Whiz is in the press, often after hearing some version of the question "what went wrong" for the millionth time. Or something sounds elusive because it's supposed to be. I have nothing against the press, but I respect someone's opinion to not play ball at times.
PS - he might be totally arrogant. Just saying we are judging one version.
I had the opportunity to meet and speak with Whiz in person. He was really nice in person but at the same time carried himself with an air of confidence. I felt intimidated but hey he's the head coach of the Arizona Cardinals.
He spoke with me some and even insisted that I take a photo with him. It was right before the second round of the Draft so I didn't want to bother him but he would have non of that. Other than attending the Super Bowl, it was really the highlight of my Cardinal fandom.
I think some here mistake his confidence for arrogance.
