That's leadership. Butch was worried about putting people in place that could take him job. Dooley was pontifical, Pruitt was not afraid of a smarter than him staff, he just didnt let them be who they are and handcuffed them.
You are definitely right. It is an indication of a significant difference in leadership styles.
My take on Dooley is different. I think he was a baby seal trying to find a safe place when Jaws attacked. IMHO, he realized within the first year that the job was too big for him and beyond the commitment he wanted to give regardless. By the end of the 2nd year he was broken and wanted out. What you saw as pontificating... I saw as a desperate guy thrashing around trying to look like the coach he knew he wasn't.
I think the guy literally quit in year 3. He still went through the motions but there was almost no effort in recruiting. He seemed resigned to his fate.
Pruitt was more subtle than you might expect... but after a while his "it starts with me" began to be code for "I have to deal with and make up for incompetent people around me". I wanted Pruitt to succeed and still think he's a good teacher of the game. I think he can still succeed as a position coach or DC. I don't think he can succeed as an HC without changing quite a bit. He's probably where he needs to stay.
I never bought into Jones at all. I think he was nothing more than a used car salesman constantly overselling himself and his "product" to everyone- recruits, players, fans, administration, media, etc. That's why it had an initial "splash" effect.... and why it was so short lived. The guy had no substance.
