Josh is one of those unique talents that when he makes a mistake, it's amplified by a factor of X.
I've lived in the Boston area for over 30 years, through all the Super Bowls, and witnessed the same thing about Tom Brady.
He'd throw a pick or fumble (yes, it actually happened) and people would be dumbfounded-- must be someone else's fault, he's a unicorn, etc, etc.
Fortunately for Brady, he had SB success early in his career, and didn't have the same weight of expectations hanging over him his entire career.
Deep down we all know it-- life isn't always fair.
