My thoughts:
I believe Dak shows more leadership than any QB that has been a Dallas Cowboy except Aikman and Staubach. He stepped into the job after Romo went down and embraced the starting job. Did the team sculpt the play calling to not overwhelm him? Sure. But his leadership was revealed from day one. The team respects him and sees him as their leader. Because of his leadership. Part of that leadership entails his off field decorum. As much as Roger was Captain America and Aikman was an extension of Jimmy Johnson, Dak Prescott fits the America's Team moniker because of his behavior on and off the field.
Part of this behavior is his unfailing dedication to improve. The guy works on his game constantly. He is a first in, last out type of player. Dak leads vocally, but his work ethic is without question in the very top of Dallas Cowboys that have come before. He is going to work on his game, strength, and mental aspect of film and learning his job, more so than I have seen other QB in this franchise display. If you know the work ethic of Michael Irvin when he played, Dak is shoulder to shoulder with him as far as being the best he can be.
What I read here about Dak's skill set, in most cases, does not reflect what I see on the field. Does he occasionally throw and errant pass? Yes. All QB's do. Shorter passes tend to be a it high. But that is livable since he also is very frugal with interceptions. Last year was a perfect storm of mistakes, and Dak shared in them. But this filtered throughout the team. I believe the entire team is better than what we saw last season. That includes Prescott.
Overall, I am satisfied with Dak. I think he can be a difference maker. All QB's must have talent around them. That includes Brady. My belief is, with the team playing to its potential, Dak can lead them to an NFC Championship game. From there let the chips fall where they may.
