The Dallas Cowboys will host the San Francisco 49ers this weekend in the opening round of the NFL playoffs.Last year, Dallas missed the playoffs mainly because of an injury to quarterback Dak Prescott, who missed the rest of the season due to an ankle injury.Dallas Cowboys@dallascowboysSetting the standardAfter a record-setting night in Philadelphia, @dak becomes the first QB in franchise history to be named the NFC Offensive Player of the Week three times in a season.#WPMOYChallenge Prescott7:54 AM · Jan 12, 20222404390Setting the standard❕After a record-setting night in Philadelphia, @dak becomes the first QB in franchise history to be named the NFC Offensive Player of the Week three times in a season.#WPMOYChallenge Prescott https://t.co/yqXsOZDwcADespite their success this year, however, not everyone seems to be sold on Dallas. NFL Network analyst Maurice Jones-Drew is not buying into the team just yet."I think the Cowboys have the talent and the ability to do it. But they haven't put it all together. Does that make sense? When you look at their their their wins, right? It's been it's been against the NFC East... The Dallas Cowboys they're not that good to me. I don't think the Cowboys are a Super Bowl team now like maybe with the upside of a title game team."Jones-Drew is right as Dallas has struggled against opponents from different divisions this season. In fact, they were almost swept by the AFC West this season. The only team they defeated from that division was the LA Chargers.The team has the talent to make a serious playoff run, but do they have the will? With a lot of their losses this season, there have been several self-inflicted wounds that may have cost them games, so the question remains, can this team overcome that issue?Why have the Dallas Cowboys struggled this season? Quarterback Dak PrescottThe biggest dropoff for Dallas in their losses has been mainly on offense. Despite scoring 51 points last Saturday against division rival Philadelphia Eagles, they struggled the previous week to score only 22 points against the Arizona Cardinals.The saving grace for this team when they have struggled has been their defense, which has kept them in games this season. They had the most takeaways of any team in the league with an average of 2.0 per game.Then there is Trevon Diggs, who led the league with 11 interceptions in the regular season.trevondiggs.eth@TrevonDiggsThank you god twitter.com/nflonfox/statu…FOX Sports: NFL@NFLonFOXThe only player to record double-digit interceptions this season @dallascowboys CB @TrevonDiggs is your 2021 Int leader!2:32 AM · Jan 10, 202210571655The only player to record double-digit interceptions this season 🔥@dallascowboys CB @TrevonDiggs is your 2021 Int leader! https://t.co/pfHc6SEutKThank you god 🙏 twitter.com/nflonfox/statu…If Dallas to make a run this year towards the Super Bowl, it would most likely be because of their defensive prowess.If the offense can play the way they have played in the earlier part of the season, they could be a legit Super Bowl contender. However, if they struggle as they have been known to do this season, they may be out of the playoffs in just one week.
