Lets compare his roster first up and during his second stint. Like looking at Parra's roster 2018 and now. Poles apart and poles better helps with better results.
And with Cleary, someone in the background constantly looking over his shoulder and making decisions that undermines him, intentional or not, is not ideal in achieving good results. Pou, as you know, stats are misleading unless you're comparing the same roster, as it changes each year, which is impossible to do so your statement is rubbish.
