I hate him as an announcer, but he was a phenomenal QB. He was the most accurate medium-deep to deep thrower of his era, and it opened everything up.
Just for some perspective, look at his accuracy during his prime from 1991-1996 (before all of the back injuries). Those numbers in that era were extremely high. https://www.pro-football-reference.com/players/A/AikmTr00.htm.
from 1992-1995, the Cowboys’ passing offense was 3rd, 3rd, 2nd, and 1st in net yards per passing attempt.
