The Great Ruck Debate.

[LP]

Its like keeping a stat on knocking the ball forward/out of a pack. Could go to you, could go to the opposition. What does that stat tell us? Nothing.
If you had a stat of knocking the ball forward/out of a pack to your teams advantage, then it at least gives you some idea of cohesion amongst your midfielders in a pack.

Again, the problem is visible here in the definition, because you can't determine what was deliberately knock on to advantage and a otherwise lucky fumble. A player might be credited with many knock ons to advantage, that result in no scores, but another player who picks up the foot cleanly and hits a target never gets credit for a knock on while creating many score assists.

It reminds be of the NRL knock on, possibly random due to the nature of an oval football or a clear assessment of clean ball handling? In isolation it means nothing.
