Let's hope what might be called the 'Richie Rule' - the new breakdown laws being trialled at Mitre 10 Cup level - never go any further because they may spell the end of one of the great strengths of New Zealand rugby.
The trial rules (it must be acknowledged it is early days; coaches and players may not yet be quite to grips with things) could signal the demise of the ball-burgling No 7, openside flanker - the greatest exponent of whom has been Richie McCaw. The changes make such a difference more than one commentator has been moved to wonder whether McCaw, had these rules been in force when he was on the way up, would even have made it into the All Blacks, let alone play 148 tests.
The cold, hard reality is that the ball-stealing No 7 - a position the All Blacks have perfected ahead of any other country with the likes of McCaw, Josh Kronfeld, Michael Jones, Jock Hobbs and Graeme Mourie, among others - would be extinct under these rules.
Rugby's stifling, boneheaded laws governing the God-awful breakdown and offside laws do need to be changed. Just not this way. Under them, a breakdown is deemed to be formed when only one attacking player is over the tackled ball on the ground. From that moment, no player can touch the ball with their hands.
So the only opportunity for a McCaw-like turnover is for a defending player to get to the breakdown before the first attacker arrives. The tackler can't bound to his feet and grab the ball from the tackled player; he must now retreat. However, his team-mates can drive in and roll over the top of the tackled player, winning the ball that way.
