Both training injuries. WTF is Cheika trying to do? We seem to suffer a whole lot more injuries in training than we do in the games proper.
The following comment is for information only and is not pro or anti Cheika:
In 2014 I attended one of the Waratah training sessions on the ground outside the SFS. Just a single session so I can't know whether and how many sessions during the week were the same. It ran for under an hour and consisted of three sections: About 20 minutes of contact drills (1-1, 1-2, 2-3), a short skills session (forwards - scrums and lineouts, backs - passing drills) and then about 20 minutes of full teams' opposed training. The intensity was 100% game pace. I'd never been to a training session before and the intensity surprised me. Maybe it is typical for all Super teams, I don't know.
My point is that this is the way Cheika always trains teams. High intensity, short duration. Having watched it my surprise is that there are not more training injuries. I came away thinking that elite sports training is tough, very tough. In my amateur sporting days I never trained with that much intensity - probably why I never went further than amateur lower grades.
As an aside. It was only a couple of games into the season and I saw this Islander back I didn't recognise, absolutely smoke his opponents in the drills over and over. A couple of games later he made the team and Alofa Alofa made his way into NSW rugby history. You could see on the training paddock that he had something special.
