Is Dak Prescott good enough to lead this Cowboys team to ultimate success?   This Cowboys team has only scored 29 points in their last 2 playoff games.   Dak hasn't been terribly good in those games.   Dak Prescott is a solid QB but they are going to need him to step it up this season compared to last season.Fairly or unfairly, when QBs don't win they get labeled.  This is the year for Dallas to win it all.   That makes it a critical year for Dak Prescott to prove he can lead the team to ultimate success.
