We all get he has thrown the ball a lot, that has never been debated, he throws a lot. He is also one of 4 QBs to throw for more than 4200 yards and 22 or less TDs, he's done it twice.
Look at his efficiency compared to other QBs. He is bad compared to his peers, but yards impress people for some reason.
When Marino threw for 5,000, there were only two others that even threw for 4,000, and Simms barely made that at 4,044. When Staff threw 5k, he was the third highest in the league that year, 10 threw for more than 4k. Even in that glorious year he was 13th in YPA. So again we get he throws the ball a lot. Good for him.
