I disagree. The Pegulas didn't make botteril an idiot or the coaches bad coaches...
Also, we don't know the extent of the Pegulas meddling. A lot of people are very sure about this, but I've yet to see a report that was something more than feelings about what their meddling actually was... this reminds me of the years that people freaked out about Overdorf on the Bills as some secret GM.
It's long been confirmed that Erhoff and Leino were directives from Pegula, because he wanted to 'make a splash'.
Most of the sports reporters in town will tell you off the record that JB didn't want to move ROR but was forced to by Terry. Same with the max extension for Skinner.
There has been plenty of non-message board chatter for years that Krueger was 100% a Pegula hire, and JB didn't want to do it. ( And this was all before we saw how much of a snake oil salesman Ralphie was. )
We all saw the video of Pegula in the room during the Hall negotiations talking about how this was a move to push them towards a Cup.
Even if you assume some of the rumors aren't entirely true, which is fair, there's enough smoke here over a decade to reasonably infer the guy sticks his nose into things repeatedly.
EDIT: Lest we also not forget when he hired a President of Hockey Operations ( LaFontaine ), who gave Tim Murray direction on what to do with Millsy. TM didn't like what he was told, so he ran the end around. A non-meddling owner would have said 'Patty is the Pres of Hockey Ops, so this is his decision'. But Terry stuck his nose in and overruled LaFontaine, which is why he quit.
