Jim Mora didn’t like Rizzi chewing out Matthew Hayball

That's clearly your opinion on the matter. I think you're overlooking that Hayball plays on the unit Rizzi coaches. Payton would yell more at offensive players than defense. There's probably a tendency of coaches to get more quickly frustrated with players that aren't doing what they have directly coached them to do. I think that was as much a factor as any "pressure" he might have been feeling, but that's just my opinion.
We very well could both be right. I was not knocking him. I think any coach would feel a little pressure when they are; coaching in their first game on the road, their first game in front of their family and peers, their first game back in their hometown, and in a must-win game where they are playing horrible against the worst team in the league.

I agree that he will be more passionate with the sp teams unit because that is his "baby". Though they have been very middle of the pack all year, I get the emotion. 32 in avg. 28th in net. 26th in punt return yards
