Why is Courtois 121 Bunz?

I literally spent so much time from upgrading my 116 Courtois to a 121 Courtois Max rated, and has 2 on diving 2 on shot saver 1 on GK Rush. Apparently those stats were supposed to make Courtois the "best" but according to ME. It's **bleep**not. His card is horrible. He conceded multiple easy shots that i over work myself into defending trying just to survive in Legendary ranks. I thought he was gonna be good. EA shows me this when I pack him in the drafts, but he comes out horrible. Is there any way for EA to buff him? Or even make him better?
