I would reduce the number of substitutions/interchanges to reintroduce levels of attrition in our sport. As eluded to by the OP, tackling of this nature in the amateur game is negated due to the lack of fitness of the players.

If we reduced the number of interchanges, players wouldn't go into tackles in such numbers or with such intensity due to a) reserving energy b) fatigue

Far too radical

Except they weren't doing that out of some benevolent notion of service to the sport. It's because they were knackered and no-one else could get there in time to support the tackler.

To FORCE that to happen now, rather than it being a natural part of the game, would be a very radical step.

Limit the number of wouldbe tacklers to two, if a third joins in ref calls held immediately. Ban scoots from dummy half. The dummy half must pass from the PTB.

It seems some people really have, er, issues with this, doesn't it?

A thread started in response to a Saints tackle which caused a horrible injury, by post two it's blamed on Wigan.
