In recent months a particular ruck law has been taken advantage of by wily players, but Brian O'Driscoll believes that the rule is detrimental to the game and should be changed.
The current laws allow players who are part of a ruck and have stayed on their feet to interfere with the arm of the scrumhalf once they have picked up the ball.
If the defending player can manouver themselves deep into the ruck and close to the opposition 9 while staying on their feet, it becomes extremely difficult for the scrummie to get the ball away.
O'Driscoll highlighted an incident from Scotland vs Wales on Saturday which saw Scottish prop Zander Fagerson take advantage of the law and win a turnover for his side.
BOD then took to Instagram to voice his concerns:
This ruling has to be changed. Does nothing for the game. He's actually offside too as he's part of the ruck but are we trying to play or spoil. *easy Scotland it's not just you guys.
O'Driscoll does get a slightly mixed up here as the fact that Fagerson is part of the ruck is the reason he is allowed to go for the arm of the scrumhalf. However, the referee should have awarded a penalty to Wales as the prop had not stayed on his feet.

Players who have been seen taking advantage of this specific rule include Stuart McCloskey, Caelan Doris, and Maro Itoje.
It is hard to argue with O'Driscoll, however, over his opinion that it should be banned, as it should not be made so difficult or risky for a scrumhalf to perform his most basic task.
It brings up memories of the offside law which Italy famously took advantage of against England in the 2017 Six Nations. A law which was duly changed by World Rugby to avoid further mayhem.
