I guess it comes down to how accurate the coaches want the info to be.
That depends on the extent to which coaches rely on statistics. I'm sure there is enormous variance across teams, but I'd guess that some of the European clubs are the most advanced. I would also say that most teams relying on third-party stats services do not take their statistical analysis seriously. If they did, they would probably do their own coding because they would have game plan or player specific focuses.
Rugby is a bit tricky with stats because the season is quite short, making sample sizes small and easily distorted by particular games or scenarios.
