Well, it's not a holding foul, but it could rise to misconduct. This provision is about game management and trying to avoid what was seen as a growing problem. The idea was that the warnings pre-restart was a better solution than calling lots of fouls on corner kicks to get the message across--and it's a lot harder for the player to complain about the holding call if he was warned about it before the kick was taken. All that said, it's another question as to whether that belongs in the magic book--i think that kind of preventative refereeing was being done by many when appropriate long before it was in the book.And is a push allowed if it doesn't impede the opponent's progress, or a kick?
It's just playing advantage...
And if it's only holding if it impedes an opponent's progress, how come it's holding even if the ball is not in play and no one's moving?
" with these situations:
• the referee must warn any player holding an opponent before the ball is in play
• caution the player if the holding continues before the ball is in play"
It's no wonder the laws are twice as long as they used to be.
