Cowboys are among the favorites to reach the Super Bowl

Within a month of starting the NFL season, we discovered that there are no dominant teams.

Games have been closed and several of last year’s Super Bowl contenders are struggling.

While we still have a lot to learn about all the teams during this 17-game season, here are my top three Super Bowl contenders in the National Conference.

Dak Prescott could end up winning the MVP (Most Valuable Player) award if he continues to perform as well as he has for four weeks.

He is completing 75 percent of his passes and has 10 touchdowns against just two interceptions.

The Cowboys are averaging 31.5 points per game and both Ezekiel Elliott and Tony Pollard are running well, behind one of the best offensive lines in the NFL.

New defensive coordinator Dan Quinn has helped, but

they’re still giving up too many yards, but allowing 24 points a game is acceptable given the way the offense is playing.

Tampa Bay recorded a 19-17 victory on Tom Brady’s return to New England, bringing his record to 3-1.

Brady’s numbers have been a bit off so far this season, but it’s not a cause for concern.

Brady continues to be an exceptional leader and winner and will have this team well positioned in the Super Bowl chase.

But if there is a cause for concern, it is in defense.

In particular, passing defense has been a problem and they have been devastated by injuries in the secondary.

The Buccaneers, who are still excellent at defending the run, will need to fix that.

Green Bay has already forgotten the 38-3 season opener loss to New Orleans and have racked up three wins since then.

They are still led by Aaron Rodgers, who has eight touchdown passes in the last three weeks.

The defense ranks sixth in the NFL in yards allowed per game.

Perhaps most importantly, the Packers have a dominant position in the NL North Division.
