I don't think you can use the word unprofessional in the same sentence with Bruce MaCavany. No way he can be described as that.
Sorry?
He is commentating athletics at the Olympics (which he has done since at least the 1980s iirc), and yet he needs to go looking for a rule book to acquaint himself with how they decide the winner of a race in a close finish ... how does that not fit the definition of the word "unprofessional"?
