"Sources say what he specifically asked for was a two-year contract extension for himself, and extensions for his coaching staff so that the assistants were all on the same cycle. They were off kilter because he had to bring in several new coaches in 2014 after Mike Pettine took several of his guys to Cleveland last year."
