There definitely needs to be some kind of review to look at the root causes of the annual injury crisis. Scotland are particularly reliant on a number of key players who can be the difference between winning and losing a game. As such they are more liable to be targeted and roughed up but that can also happen to the other nations. It doesn't help when the exiles are forced to play for their clubs the weekend in between 6N games. The 'freak' crisis is probably down to the sum of a number of different factors combined and is accentuated by the lack of strength in depth.
