I don't think anyone's said this, but I reckon that there's no real meaning to this squad announcement. There was no build up to it, no big interviews about the selections, and the next international fixture is still in 4 months. When the AIs come around, Lancaster will pick another squad from the EPS and Saxons judged on the start of season form. (And Haskell will probably be in it.)
If this is the case, the main gripe I have is: what on earth does Nick Wood have to do to get anywhere near England!? He was the only prop to be nominated for player of the year last season, but he doesn't even make the Saxons? It might be said that he's quite old, but he's still younger (and a lot better) than Matt Stevens.
