Yea its the cerebral part of his game that hasn't developed. People have blamed McVay for taking too much control early on and maybe stunting his growth there... but obviously McVay felt he had to for some reason. To be in year 5 and have his awareness and read defenses like he does is not acceptable IMO. When people are open and he's in rhythm, he puts the ball on the money. But to win big games against great teams thats just not enough.
As great as he was in the NFC Championship game, and I truly believe he won us that game single handedly and outdueled Drew Brees... he was just as bad if not worse in the SB. And since then he just hasn't been the same.
