Minnesota's Kirk Cousins threw for 265 yards and two touchdowns in a triumphant NFL return to Washington on Sunday while the Buffalo Bills were upset by the New York Jets.
Cousins, who spent six largely frustrating NFL seasons with Washington before joining the Vikings in 2018, sparked Minnesota over the Commanders 20-17.
"I knew I was going to be emotional pulling in, seeing the player parking lot where we used to hang out. I about shed a tear," Cousins said.
"But we had a job to do, and we got the job done."
The Vikings, who trailed 17-7 in the fourth quarter, improved to 7-1 overall -- their best start since 2009 -- and stretched their win streak to six games, each victory coming by eight points or less.
"We feel like we're using too many of our lives right now. We need to win a little more convincingly," Cousins said. "We've got to find ways to win a little better. We've got to play a little better.
"But I'd much rather have these conversations in the meeting room tomorrow after a win."
Cousins completed 22 of 40 passes, including touchdown tosses of nine yards to Justin Jefferson and 12 yards to Dalvin Cook, and guided a six-minute drive to set up Greg Joseph's winning field goal with 12 seconds remaining.
"We're finding ways to win," Cousins said. "We're finding the inches. We grind on them and keep trying to pull them out at the end."
At New York, the Jets drove 86 yards to set up Greg Zuerlein's 28-yard game-winning field goal with 1:43 remaining to beat Buffalo 20-17 for their best start in 12 years.
Bills quarterback Josh Allen ran for two touchdowns but Jets defenders stifled the NFL's top offensive unit as Buffalo fell to 6-2, still ahead of the Jets (6-3) atop the AFC East division.
Miami improved to 6-3 in the AFC East as Tua Tagovailoa threw for 302 yards and three touchdowns in the Dolphins' 35-32 victory at Chicago.
Chicago's Justin Fields, who had three touchdown passes and a touchdown run in a losing cause, ran for 178 yards to set an NFL one-game regular-season record for quarterbacks, five more than Michael Vick's old mark from 2002.
AFC East rival New England improved to 5-4 with a 26-3 home rout of Indianapolis as Mac Jones threw for a touchdown and Jonathan Jones returned an interception 17 yards for a touchdown.
