A man who can admit he made a mistake is humble. It shows character. People who can't admit they made a mistake are very hard to deal with. They tend to alienate those around them and cause resentment. Not qualities that make for good leadership. Add to that the immature tantrums and it exacerbates an already poor environment. This was evidenced by the lack of discipline on the field by the players last year. Repeated stupid and undisciplined penalties that cost the team games. I'm making this up or exaggerating things. These are facts and it was readily apparent and commented on repeatedly throughout the games last season.
I agree with this. The example set by a coach filters down throughout the team.
In terms of describing Jason I would even take it once step further...you have basically described a Narcissist. Narcissists have extreme difficulty taking ownership of anything that might paint them in a bad light. They also have extreme difficulty with self reflection.
That fits Jason to a tee.
Jason has demonstrated that he is so wrapped up in himself that at times he loses all semblance of reason and control. Watching one of those displays is embarrassing.
At least if he had some ability for self reflection it would open the door for fans to see that he has the ability for growth.
Sadly that has not been the case so far. Could it change...sure.
Is it likely to change....no.
I say that because if Jason was likely to grow as a person then there would be some evidence of that so far.
He is what he is.
