Explain like I'm 5

How is it that just a couple years ago that Baker got a perfect passer rating at Lambeau with 22/28 and 381 with 4 TD and no interceptions

But he only gets a 90 yesterday with 29/33 379 and 2 TD with no interceptions

You're telling me that with two more missed catches and two more yards and two more TDs you get a 60 point swing?
