They also averaged over 10 yards per ATTEMPT, factoring in incompletions / etc. For comparison, the New England Patriots Average something like 7 and change.
No sir, they avg'd about 8.7 per attempt since 03. They had just under a 50% completion rate at 17.6 yards per attempt.
Only two teams have averaged 10 yards per attempt for a season since 99: Auburn 2004 and Hawaii 2006. Joe Hamilton had over 10 yards per attempt but GT overall didn't.
Here are Navy's numbers each season with national rankings that I think are correct:
2007: 16.7 YPC (1st), 9.11 YPA (3rd)
2006: 14.2 YPC (3rd), 6.5 YPA (below avg)
2005: 20.3 YPC (1st), 9.51 YPA (1st)
2004: 18.3 YPC (1st), 9.77 YPA (2nd)
2003: 17.6 YPC (1st), 8.25 YPA (20th)
Of course they were first in rushing per game every season except 2004, when they were third.

1st in yards per completed pass.
1st in yards per attempted pass.

3rd in yards per attempted pass.
