Bills fans have a petition to ‘reinstate’ fired coach Sean McDermott. Some Bills fans aren’t letting go of Sean McDermott just yet, and one fan’s reaction has turned into something much bigger than anyone expected. There’s a petition at Change.org calling on the team to “reinstate Sean McDermott to the Buffalo Bills.” It had nearly 3,000 signatures as of around 6 p.m. Wednesday. By 8:30 p.m. Friday, it had more than 62,000 signatures.
