It's not that crazy really. Bills are stuck paying him this year anyway so rehiring him saves them money. This keeps stability with the assistants too. Bills felt they progressed last year, so if they can continue that and win another game or two it could produce the coveted playoffs berth. Pegulas are bridge builders, I can see them working to smooth differences between marrone and brandon. The guys a fracking billionaire, something tells me he's not averse to managing some negative PR for bringing him back. If it saves money, keeps continuity, and is seen as giving a realistic shot at playoffs next year, why not?
