Depends on how you look at it, is getting into the playoffs and getting destroyed in the first round of the playoffs someone superior to not making the playoffs?
Yes, because if the Cowboys build a team that can overcome the weaknesses of a certain player or even a position group, they can make a title run.
In NFL history quarterbacks like Stan Humphries, Chris Chandler, Kerry Collins, Trent Dilfer, Jake Delhomme, Matt Hasselbeck, Rex Grossman, Jimmy Garopollo, and Nick Foles have reached the Super Bowl. How many Hall of Famers are in that group?
If they can get there with the right team, Dak Prescott certainly can. But conditions have to be right, and the Cowboys haven't shown they can provide those conditions.
So we can just hope they get lucky one year, or spend the next thirty years waiting for the next Patrick Mahomes to fall into Dallas' lap.
