The Great Ruck Debate.

[PaulP]

......................................... 

There’s no hard and fast rules about one or two rucks.  It depends on the opposition, whether the rucks can do more than take part in ruck contests, game plans, and the other players in the 22.........................................

Not just rucks, but any selection decision for game day has to be horses for courses. Whatever resources are at the club's disposal have to be marshaled as and when required. Anything else is formulaic, dogmatic thinking.
