The Scots and Italians have relatively settled sides and although they don't have much in the way of spectacular players, the likes of Jacobsen, Ford, Blair, Cusiter, Lamont, Castro, Bortolami, Parrisse etc etc etc have all got 40+ caps and know what international rugby is about.
The performances were scrappy, but that's to be expected when taking on 2 sides full of gritty 'spoiling' players. Taking these guys on with several new caps was brave but it gave valuable experience and this can't be underestimated. With limited time to form a side the priorities MUST be the basics of a forward pack, kicker, and a centre to cross the gain line.
Lancaster got this spot on because with the amount of new caps, he knew we wouldn't have much ball so there would be no point trying to bring some spark to the back line. Now that he has had a bit more time, the new pack is starting to form combinations and acts as slightly more than the sum of its parts he can put some time into the backs knowing they will get some ball.
The key question is what would anyone else have done, and if Mallet, Henry, Robinson, Woodward or even David Cameron was in charge, I expect they would have done exactly the same because that's how rugby works.
You can blame SL for his substitutions all you like, but again, most coaches would agree that replacing men of their first starts for guys with 20+ caps in the last 20 minutes will close the game down. These players messed up, not the guy that chose to put them on the pitch IMO.
