Skipped pages 2-5, but kind of doubt I missed much in the way of new content.
To get back to the issue in the thread, I do think who has the final say on the 53 man roster is important and something a Bills fan would reasonably care about as well as feel some justified entitlement to knowing about.
If the answer is Beane, then control of the team is more evenly apportioned. If the answer is McDermott, then he obviously has complete control. There is a difference between the two, although not one that should impact who would get canned given the matched contract lengths. The difference speaks more to whether or not Beane is a true GM. If Beane does not have control of the final 53, then would his position not be better described as head of football operations, director of player personnel, or something similar.
If the answer is anyone other than Beane or McDermott... yikes
Probably answered in a press conference, so please forgive me in advance, but does the head coach still report to Brandon like did Marrone? (link)
(Of note, and per that link, I was unaware that Rivera reports(ed?) to Gettleman.)
