Almost impossible to quantify like that for me. The margins at test level are so tight that even tiny improvements in one area can lead to marked improvements on the scoreboard.
mm's difference between taking a try scoring pass and knocking on. Fractions of a second difference between delivering a try scoring pass and being intercepted etc...etc..
That said, England need to make a difference in quite a few areas in order to beat Wales, and in all honesty I don't see it happening.
Feel the rain like an English summer. Hear the notes from a distant song.
Stepping out from a backdrop poster. Wishing life wouldn't be so dull
