So what? All goalkeepers are mad when they concede. Especially when it's off of a deflection. It's a cheap goal.
Would you rather Bonucci step out of the way when the other team shoots at Juve's goal?
If Oscar shoots and Bonnucci lets it go and it goes in, it's still Bonucci's fault. I think he does what a defender is supposed to do, he's just unlucky. I'd rather a defender attempt to block a shot than not. From a former GK's perspective.
