His worst year for England, for win ratio or for PD, was 2021 - with all the covid disruptions and discrepencies.
win ratio of 40%, PD of -1.8
Within the last 26 years (taking the worst calendar year for each coach/cycle)...
SCW(1) managed 0% and -8.8 in 1997
SCW(2) managed 38% and -3.6 in 2004
AR managed 27% and -7.2 in 2006
BA managed 53% and -1.2 in 2007 (including a RWC final)
MJ managed 25% and +5.9 in 2008 (or if you combine MJ's reign with MJ's telling RA what to do - 17% and -2.5)
SL hit 50% and +5.4 in 2012 and again in 2013 (well, PD of +5.5 that year)
EJ(1) managed 46% and +2.5 in 2018.
None of them fought Covid (though SCW did have BSE)
I could break it down by 6N; but I don't have that one to hand, and... I can't be arsed.
I don't like defending Eddie at the best of times; and today... it looks like I might die on the rugby pitch this afternoon (hail and lightning forescast for this afternoon, and my fat-old-blokes walking rugby team are entering the club touch tournie against the 1stXV, 2ndXV, LadiesXV and Colts XV - I'm the youngest at 47, and I think 3 of us have all our own hips and knees)
