I raised that question short time after the Rams aquired him. He was streaky and erratic all his time with the Lions and has shown the same here. He looks like god playing QB one game and then turns into a JAG the next game.
He had some absolutely magnificient games in a Rams uni but also we have seen 4-5 clunkers where he sh.it the bed. Last exhibit was the Vikings game on Sunday.

So to answer your question: No, I do not think he will be able to play 4 good to very good games in a row in the postseason where he has to face the best the NFL has to offer. That erraticness is what puts him in the second tier of NFL QBs. The good to very good ones but not elite like a Brady, Rodgers, Mahomes
Rams have proven they can win even when he has one of his clunker games in the regular season but not yet in the postseason.
Getting back Akers would certainly help a lot because it would ease the pressure on Stafford .

Go Rams!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
