UPDATE: A Scout.com source within the Bills organization stated that Doug Marrone wanted a two year extension. New ownership wouldn't give it to him. Marrone was livid about their refusal to extend him and this is why he opted out of his contract.
"Doug Marrone has opted out of his contract as the Buffalo Bills coach and is now a free agent to pursue other jobs, per @mortreport and me."
Schefter and Mortensen added that Marrone was able to leave the Bills with his 2015 salary of $4 million without it counting as an offset against any future salary. The New York Jets are the favorites to land Marrone according to Schefter.
Tim Graham of The Buffalo News added that Marrone was playing hardball with the Bills in the hopes of getting an extension for himself and his coaching staff.
"League source: Marrone asked Pegulas for an extension and was told no. He then asked for extensions for his assistants and was told no."
Marrone finished his second season with the Bills with a 9-7 record. Overall, the Bills went 15-17 under Marrone. Buffalo's offseason just became very interesting with their head coaching position opening up.
