Decastro was trying to end the situation by containing Garrett, and he went all barroom brawl and beat Garrett who was defenseless. They fine and suspend guys for hitting a defenseless receiver who was going over the middle during actual game play. This was a guy being held by a 300lb linemen trying to deescalate everything, had his arms pinned and Pouncey thought that was the time to be punching and kicking him, whats that say about you if you think that's an okay action? That's not football that's not life and belongs no where
Pouncey should absolutely be suspended. But if I was on offense, and someone hit my QB on his bare head with a helmet like that? I'd probably be suspended, too.
