It looked like Rudolph was none too pleased with being taken to the ground and started grabbing myles’ head/helmet . Myles responded to this by returning the favor and grabbed Rudolph’s head/helmet. While getting up, Myles pulled on Rudolph’s face mask and ripped his helmet off.
At at that point the fight on the ground was over. Decastro then intervenes and starts to walk Myles away from Rudolph. Rudolph decides that this is the perfect time to reengage with Myles and goes after him again. Outnumbered and being moved backwards, garret responds by swinging at the (perceived or real) aggressor(s) with his right hand that still held Rudolph’s helmet, making contact with Rudolph’s head. Then Myles is (rightly) taken to the ground by a group of Steelers while all hell breaks loose.
That’s what I saw in the video clip.
the optics of swinging a helmet at a helmet-less-player’s head are bad and Myles will be suspended.
Rudolph looked like a frustrated person trying to take his aggression out on what was reachable. In this case, that just happened to be a someone he couldn’t push around.
Rudolph was at minimum a willing participant, if not the aggressor, at every point of the post-play interaction.
