I think that a good way for Deano to be a better defensive coach is to do a fair bit of study of the past years of Penrith dominating the comp from 2020 to 2024. Penrith had the lowest points scored against them out of all of the teams in those years and Deano should look at several of the games of each of those years to see how Cleary and his coaches, one being Ciraldo - defence (now with the Bulldogs) and the other Webster - attack (now with the Warriors) up to the end of 2022 and now Peter Wallace (attack) and Ben Gardiner (defence) from 2023 to now.
I am sure that if Deano could set aside a few hours every day for a week and study some games Penrith played in those years and with the different assistant coaches, particular games when nil to low points were scored against them, then I am certain that he will learn heaps. Maybe he already has and if he has, he is not smart because he hasn't learnt anything going from results so I doubt that he has because his ego would not allow him to bend that low in his mindset.
The quality of players of course has a big bearing as well on how good or bad the defence is. All teams would also have some bad days - cellar dwellers of course very bad days.
