Why has Launchbury been called up?!
I mean, he's a decent enough player but he's only been back for Wasps for a week or two, after a lay off through injury!
Attwood has trained with England before, and Garvey for the Saxons - both make a lot more sense than Launchbury.
Because none of the three after going to be playing, so they might as well give Launchbury the experience of training with the senior squad. I do not agree with this, but its the clearly stated logic.
