In 2014, they finally got a change in ownership, going from the late Ralph Wilson to Terry Pegula.
In January of 2015, Pegula made his first coaching hire, adding Rex Ryan after Doug Marrone surprisingly opted out after two years and a 9-7 record in the previous season.
In January of 2017, Pegula was already onto his second coaching hire, replacing Ryan with former Carolina Panthers assistant Sean McDermott.
In April of 2017, Pegula fired general manager Doug Whaley, hours after the completion of the draft. Whaley had signed a contract extension just 16 months earlier.
