The restrictions placed in response to the coronavirus (COVID-19) pandemic have offered up its own set of challenges for teams trying to secure their personnel to long-term deals this offseason. Fortunately, it seems this was not the case for the Buffalo Bills.

The Bills took to Twitter to announce that they have signed head coach Sean McDermott to a multi-year extension:

Teams have acknowledged the looming financial repercussions that the ongoing pandemic will have on the 2020 NFL season. As a result, many have been hesitant to secure their current players and coaches to long-term deals. However, the Bills were clearly adamant about making sure McDermott's deal got done following an unprecedented offseason.

The long-term contract for McDermott hardly comes as any surprise considering how he has managed to lead quite a turnaround in Buffalo with two playoff appearances since taking over in 2017. His efforts in their improvement is magnified by the fact that they had not made the postseason since 1999.

McDermott's success with the Bills has been led by the formidable defense they have assembled in recent years. This group has given up the fewest yards and fourth-fewest points over the last two seasons. While the defense remains as the strength of this team, the offense has also made tremendous strides with the development of quarterback Josh Allen and his revamped supporting cast.

Now that quarterback Tom Brady has left the New England Patriots, the Bills are pegged as the favorites to take over as the favorite to win the AFC East.
