Super rugby

So this weekend the 2012  season of super rugby begins, lots of speculation surrounds the length and toughness of this competition. thoughts are that the competition is too long and players are getting injured and become unable to play for there respctive nations when the international season begins. National coaches are urging super rugby coaches to rest certain international players in certain games. Is this good for international rugby or does it take away from the super rugby competition. When international players are injured it gives other players who usually dont get a chance in the national team an opportunity to show what they can do at that level.
