Actually, I do not agree. Oh, yes, in terms of passing yardage, surely you are correct. But for us to be two dimensional it is not necessary to have greta passing yardage, it is necessary that we are effective when we do pass. So, QBR is the proper way to measure our passing (imho).
So, take a look at our QBR for two time periods again (the "good" passing years of 2009 and 2014 when we had NFL WR's and the "poor" passing years of 2010-2013 when we didn't):
2009 & 2014 QBR vs Top Teams 123.2
QBR vs Power 5 Teams 179.8
2010-2013 QBR vs Top Teams 100.7
QBR vs Power 5 Teams 156.1
NB- These stats are from College Football Stats site cfbstats.com. Their definition of QBR is different form some other definitions. The median QBR for 2015 is around 138, for example. This reflects how poorly we do passing against decent defenses, except in our "power" years....we were 12th nationally last year in this stat and in 2009, compared to being #86 in 2013, #35 in 2012, #14 in 2011, and #113 in 2010. That 2011 team finished 8-5 and probably should have won games against Virginia (QBR a record low of 0.20) and Utah in the bowl game. They were probably talented enough to be 10-3.
I still contend that we MUST have an effective passing game, in terms of QBR, so be successful offensively and to avoid being one dimensional.
I don't know how we get from where we are today to being effective with our passing, but I do believe we MUST be effective to avoid 6-6 and 7-5 type results.....
