Also outside of a good semi-final, the last couple of years of that cycle wasn't great anyway.
2016 - Grand slam + 100% win ratio
2017 - Champions + 90% win ratio
2018 - 5th + 46% win ratio (including a loss to the baabaas)
2019 - 2nd + 73% win ratio (though we played some awful rugby that year)
Post world cup
2020 - Champions + 89% win ratio
2021 - 5th + 70% win ratio
2022 - 3rd + 42% win ratio
Parts of those periods worst finish in a 6Ns, twice. Least tries scored, most tries conceded if I remember correctly. We ended up playing some of the worst rugby I've ever seen England play. Definitely would not say it was a good 4 year period.
