I mean...like you said, once the helmet comes off, people generally calm down because everyone realizes careers are on the line. So in response to having his helmet removed, Mason Rudolph attempts to charge Myles Garrett?
I dunno, I don't have an issue with the decision on Rudolph whether it's nothing, a fine, or a suspension: he's clearly at worst the third worst person in this situation. From what i see
A. Myles Garrett took Mason Rudolph to the ground on a football play (I did not see a flag from the officials and it didn't honestly seem to me he was held down for an exceptional amount of time)
B. Less than a second after the takedown, Rudolph is grabbing at the back of Garrett's head/helmet
C. A separation is occurring and Rudolph is pushing off of Garrett using his leg on Garrett's groin
D. Garrett rips Rudolph's helmet on as he is being separated from Rudolph by Decastro (I think)
E. Rudolph attempts to go after Garrett by going behind Decastro
F. Garrett swings the helmet at Rudolph, is taken down by Decastro, and then punched/kicked by Pouncey in a defenseless position.
From my view, there's three different potential instigation points in that that Rudolph used to escalate the situation (B, C, and E). Any of those three doesn't occur and I don't think this ever happens. I have severe doubts that most other NFL QBs ever get themselves into that situation to begin with.
I don't think the NFL would have been wrong to suspend him or at least fine him given what it led to.
We also don't know what was said if anything but I don't think it will change much.
