I do think the player like and respect Rizzi which is certainly an advantage to him. And the incident with Hayball may have been a one time thing or just how they interact. So I do agree that it was over the top under the circumstances and I don't think it was something that means he can't or isn't a good HC. The Haener thing is clearly an example of him caring about his guys.
I however do think the contrast of the Haener situation and the Hayball situation gives me pause. Maybe it's just because Haener is a QB and confidence is more important for them. Or maybe its' because Hayball is thick skinned and/or needs to be yelled at and Haener is not think skinned or does not react well to being yelled at, but it does strike me as inconsistent treatment. Some of that is clearly necessary in managing different personality types, but I do think it can wear thin quickly if things aren't going great which in this situation means if the team isn't winning.
And I think overall, yelling at guys works fine at first, but in the long run guys tune it out if you do it too often or you don't win. Payton was certainly harsh at times, but most of the time he was pumping them up and I think spending all that time pumping them up made it more effective when he was yelling. And, of course, he won a lot of games so that gained him credibility.
I just find the idea that just because you don't think a coach should go all red faced and throw his headset down in a temper tantrum, it means you want a "soft" coach. There are many levels between red faced headset throwing and "soft". It just seems like fake macho bullshirt to me.
