100%. You seize control of the division and potentially the conference, and at that point you could potentially even send Buffalo on a downward spiral. They still have to play Tampa after this. Definitely reduces the likelihood of seeing them a third time.
Both teams really need to win out to get the division, but the Patriots are probably in the best shape a WC, as they are 7-1 in the AFC. Buffalo has to play Tampa, but the Patriots have Indy and Miami at home, and they have been playing good football lately, There is still a ways to go in this season, they need to keep putting the wins up.
