As a Chargers fan I want to explain Rivers 2019 INT's since I watched every single game of his.
He threw 20 INT's last year. At least 10 of those were either the receiver ran the wrong route, receiver fell down, the ball was tipped, or it was 3rd/4th and very long and he threw in essence a 40 yard harmless INT that was equivalent to a punt.
He is no Jameis. Give Rivers some time behind a good OL and you'll be amazed and love him.
His freshman year he was in the 1000 lb club with just his squats and deadlift. That’s unheard of for a QB. No telling what he can do now. Once again, I’m not saying he is my choice but when you say athletic QB, I would say he is elite.
