The questions about getting past the San Francisco 49ers hurdle were directed at the Dallas Cowboys as soon as their latest victory was complete. Quarterback Dak Prescott bristled at the premise, but the only way for the Cowboys to change that story will be to start beating the team that knocked them out of the postseason the past two years. Dallas gets another shot at doing that Sunday night when the Cowboys (3-1) visit the 49ers (4-0) in a game with much less meaning than the losses the past two Januarys, but could impact where a rematch is played this season if the teams meet again in the playoffs.
