Honestly, let's have a frank discussion here.
Terry Pegula is 73 years old. Typically, its rare for people to get LESS stubborn as they get older.
For significant changes to happen other than Adams getting canned and Terry finding another 1st time GM to come in and hope it works out, there has to be a realization by the Terry specifically that his way isn't the best way.
Think about what they have tried:
Hired former players to help, didn't work.
Hired someone with a hyper aggressive approach (Murray), didn't work
Hired a more traditional experience and patient approach (Botterill), didn't work
Hired someone with no experience but he personally trusted, hasn't worked.
The common thread here is him. Whatever level of interaction with the GMs, however much he is doing, whether its very little or as much as we all suspect, it needs to stop.
Until either we get someone in here who he trusts and can manage the Pegulas and successfully manage the team like Beane does or terry decides to run his team differently then we will see more of the same.
