You seem to have a fundamental misunderstanding of how total passing yards should be used without context. Nobody wanted to run against our front line this year, which led to every team we played passing the ball more often than they did all year, which of course will lead to higher passing yards allowed if all you look at is total yardage. The fact that you used ECU as an example is telling. They had 468 passing yards, which sounds bad, but it took them 74 attempts (!!!) to get there. 6.3 yards allowed per pass attempt is very good.
Yea, McMaryion had a season-high in pass yards. He also had 12 more pass attempts than against anybody else all year long.
I decided to look back at the “not horrible” passing teams we faced this year, which I would define as Arizona, Texas Tech, SMU, Memphis, USF, ECU and Fresno. Out of those 7 teams, only 1 averaged more pass yards per attempt than their season average. (It was USF, if you can believe that, at 8.55 yards/att vs us, compared to season average of 8.03)
Arizona: 5.9 y/a vs UH, 7.6 for the year
Tech: 7.1 y/a vs UH, 8.1 for the year
SMU: 6.7 y/a vs UH, 8.1 for the year
Memphis: 8.89 y/a vs UH, 8.95 for the year
ECU: 6.3 y/a vs UH, 7.0 for the year
Fresno: 7.0 y/a vs UH, 7.7 for the year
