Thomas Khun's The Structure of Scientific Revolutions book is excellent on that theme of challenges to established ways of thinking. He coined the term paradigm shift in it.

I think we're seeing it a paradigm shift in reality with regards Wenger.
Emirate's years paradigm - Wenger's a cretin, look at him playing kids and selling all his best players and buying no one and being smug with fourth in the league. "Arsenal are a million miles from winning a trophey" - Michael Owen in 2013.
New data comes in: Wenger buys Özil Alexis etc
Old paradigm reaction: yeah but they were opportunistic buys to get season tickets sold. He should buy Messi to prove he's serious.
New data: Wins FA Cups.
Old paradigm reaction: cups are a joke.
New data: finishes second.
Old paradigm: yeah but Leicester won the league so Wenger's clown.
New data: plays Alexis and Theo
Old paradigm: he's lost it totally lost it.
New data: Arsenal are joint top.
New paradigm: There's only one Arsène Wenger!
When you add context and are able to acknowledge the clubs history of the last 10 years, all the 'old paradigms' are valid, apart from the weak, convenient, obscure and non-existent ones you've chosen ('there's only one Arsène Wenger...? )
While the book may be excellent, I don't think you've done a good job in relating this paradigm shift to Wengers situation. Actually, I don't think it can be done, but there's no harm in trying. It's fun.
