I see two possibilities here,
1. The tales of recurring dressing room bust ups between coaches who demand style A of rugby, and players who want to play style B.
2. The players have realised that top four is beyond them and are saving it for the challenge cup.
And no doubt niggling in the background is the vast amount of cap awarded to a certain few non performing players, coupled with the fact that certain players know they won't be retained next season.
What a mess.
