The NFL has released its 2015 season previews, and the Cowboys and Broncos are the clear winners.

The two teams will meet in the wild card game on Sunday at AT&T Stadium.

Here’s everything we know about both teams.

Cowboys: The Cowboys have been a top-10 offense for most of the season, but it’s not all good.

The offense is not nearly as potent as it has been in recent years.

With Dak Prescott returning, the offense is going to have to find a way to produce in the passing game, but even with Prescott on the field, the Cowboys are going to be vulnerable to turnovers.

The Cowboys offense has struggled to find holes in its defenses, allowing the most passing yards in the NFL (3,066).

The defense is a bit of a mixed bag.

The pass rush is very good, allowing just five sacks this season, second only to the Raiders (5).

The pass defense is better than it has ever been, allowing only two sacks in the past three seasons.

There are questions about the Cowboys defense as a whole, and it is not the same unit that it was a year ago.

Prescott has been the biggest reason for the success of the Cowboys offense.

The former first-round pick is still only 27 years old, but his playmaking ability and ability to find the end zone have helped Dallas to an average of 20 points per game.

The defense has also allowed a league-low 4,086 yards rushing, which ranks fourth in the league.

The Broncos have allowed just 11.3 points per drive this season.

The offensive line has been dominant, allowing a league low of just five.6 sacks, but is allowing the second-most points per sack (8.3) in the entire NFL.

The only bright spot in Denver’s defense is its secondary, allowing an average rating of 19.0.

It is a mixed-bag unit.

Denver is allowing an NFL-low 19.5 points per play on the ground.

The Denver secondary has allowed an average passing defense of just 21.7 yards per attempt, second to only the Giants (21.5).

Denver is also allowing a combined 19.1 points per possession on the road, second-worst in the AFC.

Broncos fans should be very happy with the offensive line, but the defensive front is a mess.

The front seven is currently struggling with injuries and the defensive line has not shown the same kind of playmaking and tackling ability that it had a year before.

It should be noted that the Broncos’ defense has played much better than the defensive back unit.

The secondary is second in the NFC in interceptions and third in passes defensed.

It also has one of the top secondary grades in the game.

If the Broncos defense can get back to its pre-snap game speed, it should be a game-changing unit.

If that happens, the Broncos should be able to dominate the second half of the game and win.

Broncos vs. Chargers: The Chargers have been in a tailspin of late, allowing 30 or more points just five times in their past five games.

The Chargers defense has struggled all year, allowing more than 20 points just once in each of their past four games.

Philip Rivers has a history of playing well with some great playmakers, and he will face a team that has had a lot of turnover at quarterback, but will be lacking some of that production.

San Diego has allowed the third-most fantasy points to opposing quarterbacks (26.5), tied for second in interceptions (7) and third-best in pass defenses (94.5%).

Chargers fans should expect a tough day from the Chargers offense, and this will be one of those days.

San Diegans quarterback Ryan Mathews is one of many who have struggled in recent weeks.

Mathews has only thrown four touchdowns over his past four starts, and that includes two of his three interceptions.

Mathew has also thrown just six passes in his past five starts.

SanDiegans quarterback Keenan Allen is also dealing with some injury issues.

He is currently dealing with a hamstring injury, and has only played in three games in 2016.

San Francisco has allowed five or more fantasy points in three of their last four games, and will be without two of their top players, Justin Smith and Vernon Davis, in the matchup with San Diego.

This will be a tough matchup for San Francisco’s defense, which is ranked fourth in sacks (16) and fourth in passing defense (92.8).

San Francisco should be looking for a big night from the defense.

They are allowing an offensive line that is second-best at stopping the run (second), and are allowing just 11 sacks.

If San Francisco can stop Rivers and Mathews and keep the Chargers off the field for much of the night, they should have a good chance at a big win.

Chargers vs. Panthers: The Panthers offense has been one of their best in recent memory.

The Panthers are fourth in points per attempt (14.1
