Other than Bill's not here. Everything was filtered thru Bill, so final player selection and FA signings were all because Bill deemed it so. That is not to say that Bill did all the leg work. From my desk, players were evaluated based on a scoring system that Bill had in place. Now, it's Mayo's show, with Groh and Wolf. I think it's likely that they will have a different type of player they want. Things that Bill wanted, things he felt were important, may be down the list further under this new regime.
What I am saying is, yes, the same guys are there, but they do not have Bill's commandments, edicts, ideologues and guidelines that might have constrained who they picked or signed. I would think these guys will have their own player evaluation system that they want, and it may take pieces and parts of Bill's system, but it will certainly have their own take on what type of player is brought in.
It takes me back my first statement. Everything was filtered thru Bill. Bill's filter is no longer in place, and these people, who have experience, now are free to design their own system for roster building.
