I am going to go out on a limb and say that most of the people posting have never owned a business, one that does seven figures a year plus, AND call me crazy but probably not one worth north of a Billion. Owners can do what they want and good ones know how to play high stakes poker. Pegs played it the only smart way. He has known for awhile Doug was out, he just wasn't going to tell you or anyone else because then his cards are on display.
Whaley could have done some real damage if canned before the draft. Pegs wasn't going to let that happen. It has been obvious since the Rex firing, Doug was out of the loop.
As I have said all along I want the chef buying the groceries and the running the show, apparently Pegs does too. In today's NFL a lot of teams (winning teams at that) are going in this direction. Pegs is an analyst by nature and he sees what works.
McD seems like a guy that Pegs understands. Someone who is all about process and method, not emotion and flash. McD will have a competive team this Year and surprise some folks. Playoffs might be a stretch given the tough sledding in December but by year 3 watch out. Brady will be done and The Bills will be a solid young team ready to contend Year in and Year out.
