I'm sorry, but how has Goff proved his doubters wrong? From what I've seen, he's the same guy he was with us- makes good and bad throws, more bad decisions than good decisions, is dicey at best when pressured, and needs a complete supporting cast to be effective. He might get you to the playoffs, but won't be why you won the game.
I don't consider myself a "Goff detractor". That's just my observations of him, and I don't feel at all like he's proving me wrong. Throwing a few touchdowns doesn't change my perspective, he did that before with us quite often. Yes, Goff will do enough to get the Lions back to respectable. But just like with us, it's the true stars on that team that will put them over the top. He isn't one of them.
