Here are the top 7 all-time passing yards for a season:
(notice how many games these guys played)
Single-Season Passing Yards (games)
4,827-Garrett Gilbert (16), Lake Travis, 2007
4,825-Graham Harrell (15), Ennis, 2003
4,822-Chase Wasson, Southlake Carroll (16), 2002
4,700-Kelan Luker, Stephenville (16), 1998
4,698-Greg McElroy, Southlake Carroll, 2005
4,678-Phillip Daugherty, Bridgeport (15), 2001
4,672-Chase Daniel, Southlake Carroll (16), 2004
If this HD QB averaged 480 yards a game, he would have been on this list in just 10 games. I assume HD went to the playoffs that year, so he should have eclipsed 5,000 yards with ease.
I think not!
