Just thinking out loud here.
Jauron being up on stage by himself would probably be a tough sell, at that very moment, to the fanbase and the media who currently favor Sherman.
If Jauron came out with Capers and Caldwell behind him, the immediate reaction would switch from fury to people rationalizing the setup.
Sherman would bring Bates to run the D and many of his old staff members. He would not wish to have many current Bills asst. coaches ( still under contract ) thrust upon him. Capers and Caldwell wouldn't be on his staff, so it seems. So he had to make a strong pitch for his plan on Wed. Granted, he may still indeed be the guy.
Jauron would be more open to suggestions for asst. coaches. Some of Mularkeys staff would likely stay, with Jauron as the hire. I'm sure he'd be thrilled to have a Capers and Caldwell on his staff. Marv favoring Jauron probably isn't a reach.
Hmmm...
Maybe that rumored disagreement between Ralph ( Sherman ) and Marv ( Jauron ) isn't too off the mark. So Marv surprises everyone with Capers and Caldwell on Friday...but to ask them to work for Jauron ?
Is this the actual setup Marv and Ralph are discussing ? HC Sherman/DC Bates and Co. vs. HC Jauron/DC Capers/OC Caldwell and Co. ?
Interesting.
