With France on 18 points now I feel that England need a BP win against either Ireland or France to win. Even if they do win both games, I don't see them getting a BP. Only other way is improving the points difference drastically.
On the other hand with Wales getting a LBP and having Italy next week they should finish on 11. Scotland also have Italy, so should get at least 10 points. If England get battered in both games and Scotland pick up a LBP on the last weekend then England could easily finish 5th again.
