From Adam Schefter: Bills OC Ken Dorsey Fired
I have lived in the Bills media market for years and have some friends that are connected with the team.
There was always some concern when they promoted Dorsey that he might be too high strung to compliment a player that was already known as "Sugar High Josh". The primary reason that Dorsey called plays from the box is that he would get too excited on the sideline. Daboll provided a calming influence on both of them.
The timing is strange, but I wouldn't be surprised if there was some kind of blowup after the game between Dorsey and McDermott.
