England should have plenty of impact off the bench at the WC, assuming these players hold their form

15. Eorl Crabtree

Thats a great bench, any one of them can come on and lift the tempo which is what you need from the interchange players.
I don't know who you have at 9 *but* I fully agree. There would be serious impact off the bench with that quartet. I've often felt that the difference between GB/England and Australia has been the players on the bench. Too many times in the past, we've gone with players who provided either:
1) reduced quality
2) no impact/nothing different
3) both (of the above)
To compound the issue, we've had several coaches who have picked a bench with an insufficient number of forwards. With 54/55 stones of bodyweight between the first three names, none of those previous downfalls would be present here!
