Umm - I think I could have arrived at this conclusion

“At the moment, we are either not batting well or not bowling well and are not putting it together.
“It’s not going well at the moment and we’ve lost four in a row apart from the rained-off game but it’s only the guys in the dressing room that can change things around.
“We’ve had five or six excellent years and the Essex fans have been spoilt for trophies but at the moment we are in a little trough, which can happen now and again, and we need everyone to get behind us.
The problem is, it's not even the right conclusion. We are not "in a little trough which can happen now and again". We are a poor T20 side and have been for years. Everyone with half a brain could see the 2019 win was a fluke. We were incredibly lucky to scrape though the group stage, we got a quarter final on a neutral stage and the pitch on Finals Day really couldn't have favoured us more.
In 2017 our record was P14, W5, L7, 2NR Finished 8th out of 9 (joint points with the bottom team)
In 2018 our record was P14, W2, L8, 3NR, IT Somehow with 2 wins finished 7th out of 9!
in 2019 our group record was P14, W5, L4, 4NR, 1T That was enough to finish 4th and we won 3 knockout matches to win the Comp
In 2020 our record was P10, W2, L6, 1NR, 1T Finished 5th out of 6
Currently in 2021 P6, W1, L4, 1NR Currently 8th out of 9.
Thats a record since 2017 of P50, W18, L29, T3. Not much of a little trough. Especially when 3 of those wins were knockout matches in 2019 which we were incredibly lucky to get to play in the first place.
