Ok, rewatching highlights again...
Game 1, I agree Crown was out of position with the first two times he was caught. The last one you mentioned? He was taking out an inhib. That's a trade worth making to have three downed enemy inhibitors. That's not caught, its a strategic sacrifice.
Game 2, he tried to make a play, that was very high risk. He times that attack a half second slower, he possibly catches Stixxay alone with the rest of CLG backed and gets a kill. He moves too soon, PoE sees it and helps Stixxay and it busts. It's not getting caught out of position. (Especially given how little was being done by his teammates, gotta try hard sometimes.)
Game 3, yep, third time he's caught out chasing the PoE kill.
So three times. I'd chalk the third one up to him being mentally checked out and not caring about the series, not being stupid. At that point it was already clear Optic was done for.
