The PI was a terrible call (non-catchable)... I agree with that. One big play that Williams did allow was that deep post on 3rd down. Everybody wants to blame PJ Williams, but in quarters coverage if you're the deep safety you have to stay deep... you can't jump a shorter route and leave that deep route open. Its inexcusable. And that' not the first time he bit a short route and hung his fellow DB out to dry.
