You gathered correctly, lol.
My first thought was how is he not in jail right now? I get that it's sports and you shouldnt be placing assault charges on people who throw punches and such but this is something totally different.
The prevailing thought is "rest of the year", I'd suspend the other Browns DL that long (Ogunjobi, for that cheapshot) and Pouncey (for punching and kicking Garrett) that long, as well as Damarious Randall for a hit earlier in the game. Sounds crazy but I'd suspend Rudolph a game for holding the other dude's facemask and yelling in his face, though him taking a game off is only for the best. If I'm Pittsburgh, I'd shut him down for the season for his own safety.
You can't just suspend Myles for 6. No way. If you let him back in it cant be until at least 2021. Make it long enough to where we forget about him as a football player, and let the conversation be "oh shit, how can you let that guy back?" Similar to Burfict, this is worse than anything he ever did. Let him earn his money as a regular joe and pray nobody gets hit with a frying pan
