Dak is the best Dallas Cowboy QB of all-time.
If by that you mean the level at which they play and the physical and mental toolset they bring to the table.
He will own most of the passing awards this year and already has many of the single season awards.
He just finished 2nd in MVP voting.
He's a physical machine with year-round nutrition, weight training and specific position training.
He knows defenses and watches insane amounts of film.
BUT he is not the best QB versus his peers of an era. Roger was on a different tier than his peers.
Aikman brought accuracy and consistency that is common now but was not back then.
All QBs were less athletic and less physically imposing 30 years ago.
Roger was the best QB of his era.
Meridith was top 5 but close to 5.
Aikman was top 5 but close to 5.
Dak is probably 6-9 but just inside a QBs peak years.
Romo was 6-9 but injuries pushed him closer to 9.
