I didn't think there was anything wrong with JWill's comments. He respects Coach K but he disagrees with him on this one issue. He's allowed to. I don't think we have any real basis to attribute some ulterior motive to him (such as "he's claiming to disagree with Coach K because he desperately wants to look impartial"). I'm taking the man at his word. He has an honest disagreement with Coach K on this issue. Fair enough.
Not sure if you follow Jay on social media, but those of us with that opinion of Jay have formed it over years of following him and his posts on social media, not simply this issue.
