Two main QB stats equate the most to success, and passing yards is not one of them.
I'm positive the OP must know this but is just posting this out of amusement.
The two main stats, when combined, almost always give a good picture of how the QB is playing
Those two stats are:
- Standard QB rating_____Dak was 14th after 5 games.
- Total TDs - total turnovers_____Dak was 8th or 9th (now lower but just counting after 5 games)
So he was in that top 10-11 range....which top 1/3 in the league.
Sometimes, the passing yards leaders ARE also the leaders in those other stats.
Sometimes, like last year with Winston, and to a lesser degree with Dak, they are not.
