It depends on the strategy and strengths of the Philadelphia Eagles. If the Eagles want to play the team that they have the best chance of defeating in the NFC Championship, they should want to play the Dallas Cowboys. However, if the Eagles want to play the team that they match up best against in the Super Bowl, they should want to play the San Francisco 49ers.
The Cowboys have a strong offense led by quarterback Dak Prescott and running back Ezekiel Elliott, but their defense has been inconsistent throughout the season. The Eagles have had success against the Cowboys in the past, and may have a better chance of defeating them in the NFC Championship.
On the other hand, the 49ers have one of the best defenses in the league and a strong running game led by Raheem Mostert. However, they have struggled against teams with mobile quarterbacks like the Eagles' Carson Wentz. If the Eagles were able to exploit this weakness and make it to the Super Bowl, they may have a better chance of winning against the 49ers.
Ultimately, the Eagles should focus on winning each game and not worry too much about the opponent in the NFC Championship or Super Bowl. Both the Cowboys and 49ers have talented rosters and can pose a challenge for any team. The Eagles should focus on executing their game plan, staying healthy and executing the plays that will give them the best chance to win.
