I really wonder why separate stats are kept. The Club statisticians would rarely be wrong by even a kick or two, so why not use them as the official stats.
The Advertiser stats are sometimes close, sometimes miles out, seemingly dependent on who is taking them.
If stats are being kept by someone relying on the players' numbers, they're in big trouble, as it is impossible to be accurate doing that. Imagine a tackle in a pack, followed by a chain of handpasses, by players running towards you from defence.
You have to call it by instant recognition of each player, whether your own club or the opposition.
