After a big weekend of NFL action, let's take a look at the big winners and losers from the Week 4 games. (Disclaimer: One game to come, Packers v 49ers)

Winner: Dallas Cowboys

The Cowboys dominated the league's best defence at home, beating the Jaguars 40-7 to take the heat off coach Jason Garrett and improve their record to 3-3. Quarterback Dak Prescott ran the ball 11 times for 80 yards and a touchdown while Ezekiel Elliott rushed for 106 yards. The Cowboys face rival Washington next up.

Loser: Oakland Raiders

The Raiders were simply awful against a not very good Seahawks team, losing 27-3 in London. The team mustered little to no offense against the undermanned Seattle defence and didn't do much to stop their offense either. It took three quarters for the Raiders to get on the board with a field goal as the pressure mounts on Jon Gruden.

Winner: Pittsburgh Steelers

The Steelers won a big divisional game against arch-rival Cincinnati thanks to some last minute heroics from Antonio Brown as the Steelers appear to have turned the corner. Big Ben Roethlisberger had a vintage performance for the Steelers, throwing for 369 yards, keeping his team in touch with the top of the AFC North.

Loser: Tennessee Titans

The Titans were incredibly meek at home against the Ravens, losing 21-0, taking their record to 3-3 this season. Marcus Mariota only threw 15 passes, making 10 of those for 117 yards. They will look to bounce back against the Chargers next up.

Winner: New England Patriots

The Pats ended the unbeaten run of Patrick Mahomes and the Chiefs, winning a thriller in Foxborough. Vintage play from Tom Brady and Rob Gronkowski in the final quarter helped the Patriots hold off the fast finisghing Chiefs in a shootout. Brady becomes the first quarterback in NFL history with 200 regular season wins.

Loser: Chicago Bears

One of the meanest defences in all of football... gave up 380 yards to Brock Osweiler. No, really they did. Albert Wilson and the old timer Frank Gore ran riot for the Dolphins who squeaked out a win in overtime.
