US Boxing head coach and some assistants cannot be in the boxers corner because of rules
<snip>
Money is merely one problem. Within a month of the London Games, the United States team still lacked a head coach. When the job finally went to Abdullah, he arrived with a big drawback: since he had worked in a professional fight during the past six months, international rules prohibited him from being in the corner during Olympic bouts. Two of his main assistants are similarly barred from ringside.
Rules are rules, and none of our coaches with Olympic experience will be able to work the corners, and thats a shame; an experienced coach can make all the difference in a close bout, said Abdullah, who was also head coach in 2004.
But our first-time coaches are capable, and well be fine.
His technical adviser, Al Mitchell, coach of the 1996 Olympic team, said experience in the corner was really important, and to emphasize the point he repeated really nine more times.
