I'm not defending him, personally I believe we could have adapted "just a little" this season, go a bit more DM focused, leveraged players like Lennon and likely be 3-6 points better off, which would have been significant.
That said, he is rigid (comparatively), I don't think we will ever see him making huge adjustments, I'm also not sure his sides will ever do the large amounts of clean sheets per season, doesn't seem to be his style.
Its not about me/you/whoever feeling better about Poch, this is a direction that club has taken, my opinion, we have had 4 managers, pretty much the same results (4th-6th) with minor variations in the style of play.
If you want better results, look at the spend, as noted in the OMT thread, City/Cheat$ki/Manure have spent $1B+, Pool/Scum have spent $800M+, we have spent $400M when looking at combined Net Spend +Wages, new manager, new players won't change that.
