I have a theory on why Currie is waiting to fire Butch and if true, Currie is more meticulous than I would have expected.
Hear me out. Butch is too young to retire. He's going to want to coach somewhere else without a doubt. Currie and boosters have seen the product he's putting on the field and know he's going to have more bad losses. With each bad loss, Butch's stock is lowered that much more.
I think Currie is going to let him keep sinking himself until Butch comes to him and negotiates a lower buyout or negotiates a resignation sum in order to leave early and save face in hopes of salvaging what little stock he has left.
This would align with what was being rumored yesterday, that Butch and Currie have spoken and are in negotiations for a reduced buyout. Currie may be just the meticulous business man/AD we've been waiting for.
Either way, I'm going to be patient and wait on Gruden!
