Refs need big balls to be successful at the top and unless there's something she's hiding I don't think she has those
If Rooney the Runt took a dislike to one of her decisions and started screaming at her she'd go to pieces

If refs need big balls to be successful, why don't they use them when they should and apply the laws correctly when face with verbal abuse? Dish out yellow and red cards every time you're abused by a player and the problem would soon sort itself.
As for her going to pieces, she's performed brilliantly under the intense media gaze already and I'm sure she'd be able to handle Shrek and his fellow 'professionals'.
