If you look at all the managers/coaches that have won championships in Chicago, there's one characteristic they all had in common. No, it wasn't that they had superior talent or that they made timely game time decisions that won the ball game... they all had mustaches. The power of the mustache. Chicago is known for it's blue-collar, lunch pail attitude and having a mustache goes hand-in-hand.
In all seriousness, in the Bears' press conference to announce the Angelo's firing, George McCaskey quickly deferred all the responsibility of firing Jerry Angelo to Ted Phillips. I'm not sure I believe that but it was the right thing to do. If you look at all front office's organizational chart, Lovie Smith reported up to Angelo and Angelo reported up to Phillips. Phillips reports up to George.
Phillips asks the McCaskeys for money to sign players per the recommendation of Angelo. All the decisions made for the team is Phillips' responsibility but George approves it.
Forget the "who makes more money" and the "who really runs this team" argument, there still is a hierarchy. Smith doesn't control the team. Angelo didn't either. Phillips manages the income and serves as the barrier between the front office and the McCaskeys. George is the final decision maker.
Here's what probably happened. George called Phillips into a end-of-season meeting. They discussed the current state of the team. They talked about the collapse and what needed to change. The conversation probably led to the current roster, ultimately leading to Angelo's core responsibility.
The conversation probably concluded with George telling Phillips that he thinks Angelo should get fired and asked Phillips what he thinks. Phillips then (probably) agreed and was given George's blessing after George told Phillips that the McCaskeys will take the financial hit.
George has also said that he doesn't feel the need to place his stamp on this franchise. Yes he does. He was named after the league and team's founder. We all knew Mike Martz was going to be the fall guy but most of us didn't think Angelo would go. Most of us wanted him to go but given the franchise's "reputation", no one really thought it would really happen, at least this year.
George McCaskey has arrived. Now the fun begins.
