I'd rather just correct your mistakes. It's a lot more fun.
Having said that, I did correct his Norwich error - he said 20,100 when it was in fact 21,500, so rather than exaggerating, as you claimed, he was in fact quoting a smaller figure.
Preston's official website quotes their season ticket sales as 'around 11,500', by the way. So he's not exaggerating about that figure either.
