Can't make a one to one comparison of rush yards to pass yards. If a team runs the ball more often, they run more clock because the clock doesn't stop on rushing plays, but it stops with every incompletion; so, there will be fewer snaps on offense (and also fewer snaps to defend against on defense) when a team runs more/better than in the past. Teams with better running attacks generally have better defenses that teams that pass more often because the games have fewer plays, resulting in fewer opportunities for the opposing offense to score. The WF offense is better (marginally) this year because WF can run the ball at a slightly higher level, even if yards a down a tick. Also, the WF passing game has been hurt by the Seringue's lingering injury.
Not saying the offense is good or even mediocre, it's not. Even so, the offense is better than last year as it helped WF dictate game tempo against some opponents, which hasn't been the case for years.
Comparing the WF offense from last year:
OL - Improved
WR/TE - Regressed
QB - Slightly improved
RB - Improved
Overall, slight improvement, but the offense is still poor and among the bottom 1/4 in the NCAA. This is the last year that the offensive woes can be blamed, in part (with increasing responsibility on the present staff) on the roster talent that Grobe left behind.
