I think you have to start with one fact and work off that for how this team is run. Booger is a part time GM and only does what he wants to do, the fun stuff. It is also a family run business so it stands to reason that family members such as Son as going to have more involvement and increased influence.
I think Booger & Son discuss everything about the cap and talent on the team like Booger discusses the sales and marketing aspects with his other son.
Any part time GM is going to be dependent on others for the heavy lifting and jobs the GM either doesn't have time to do or want to do. But in my opinion, anyone thinking Booger has turned over the decision making to anyone else on the important matters, hasn't really watched him. That's not in his makeup, he will make the decisions and he will take the heat for them. He has no problem doing that and will step up and make excuses for any employee.
As far as changing his mind, he does it all the time, think other GM's don't? They just haven't spoken to the media about it because he's the only one that does that. Hanging events like Phillips, Owens or Bryant getting cut on Son like he overstepped his Dad is ludicrous to me. When Parcells left, Booger was adamant about staying with the 3/4, what happened? Booger speaks first and then thinks about it and gets influenced by what others that he trusts think.
What leads some to think his son must be taking over is because he can't keep his mouth shut about anything and has to change a lot of the things he says. He's had so many brain trap slips that I can't keep up and don't even bother trying. I do not care what he or his son say, it is what they do that matters. They both like to talk a lot which is exactly why you do not see any other owners or GMs friendly with the media. If they don't talk to them, they don't have to explain why they're telling them something different now.
