​One of the biggest surprises this offseason was the Buffalo Bills firing head coach Sean McDermott, despite the team achieving double-digit wins and reaching the playoffs for the seventh consecutive season. While the move was hinted at for several years, actually pulling the plug on the operation was still unexpected.After all, the Bills’ goal is to win a Super Bowl, and coach McDermott had brought them to the doorstep (AFC Conference Championship) twice. Nevertheless, Buffalo decided to hit the reset button, yet they promoted offensive coordinator Joe Brady to head coach.AdvertisementAdvertisementAdvertisementBrady has never been an NFL head coach or even a head coach at any level before. Needless to say, the move was a big gamble. Now, the Bills’ organization is catching some flak.Boasting an NFL MVP in Josh Allen, one would have thought the Bills could pretty much get their pick of the litter among the best coaches available this offseason.

Yet, it appears as though the Bills had their heart set on Brady all along.BE THE GM OF YOUR FAVORITE TEAM: PFN’s FREE NFL Mock Draft Simulator“There was a Harbaugh on the market. Kevin Stefanski was a two-time coach of the year. He was on the market. There was the hottest coordinator on the market, Jesse Minter, Jeff Hafley. Everybody was talking about Hafley. McCarthy won a Super Bowl. Harbaugh won a Super Bowl. They were both on the market. And they hired Joe Brady. And when I looked at who they interviewed beyond Brady, it wasn’t great. Brady is going to be fascinating because he wasn’t the best coach on the market.”Time will tell whether the Bills truly made a mistake, or the NFL’s next great genius hire.AdvertisementAdvertisementAdvertisementAfter seeing how successful Brady had been with Allen, it does make
