The debate about forming scrums to stop the clock is assinine.
The whole point is simply to allow a team to play football.
So what the forwards don't pack... The point is stop the clock by making an effort to play football.
The rule was bought about after constant whinging by fans about teams who two points ahead with ten minutes left and begin playing negetive football by kicking the ball out constantly.
This new rule gives the team that is behind a chance for rebuttal and makes for greater excitement.
Yes teams do still try and wind the clock down, but not as foten and their efforts are no where near as fruitfull.
It was also annoying when there's say 30 seconds left on the clock and the leading team boots it out and then sits around on the ground with fake injuries as the defending team can do nothing but accept the games over.
This rule allows us more football. It is a good thing.
Not only that, it creates a good situation where by if the scores a blow out, the teams don't bother rushing to scrums and the game ends quickly as it normally would.
The other option I guess is to have time out after every error but that would mean the game goes too long.
Or time off in the last ten mins for every error, once again games would go for too long and if the scores a blow out, the game could become frustrating.
