I mean - no, of course there was no separation. You have less than 2 seconds to throw on every single pass play - there's no time for Usain Bolt to separate.
Man beaters, zone beaters, slot option routes, hell, even bubble screens at this point, are nearly impossible to throw when you are pressured immediately on every single drop back. You can't run play action. You can't take deep shots. Hell, you can't even run screens. You can get running backs sprinting out on arrow routes, or having Hunter Henry watching the QB, and not running actual routes, to get open when Brissett breaks the pocket. That's your passing game right now. And it's not going to get fixed unless they manage to pull off a trade.
