Id have to agree that it was bad keeping. If brad come out and makes him past then you have made the attacker do something, he may fluff it, what ever. But staying on your line puts no pressure on him to score on its an easy goal.
Its something we do at Spurs, and have done in my years watching them, we never ask the question, never put the onus on the other players. It always seems too easy for opposition players against us - at least make them work for their goal/assist and if they do great but the human mind can not deal with pressure very well.
