Not trying to prove anything... trying to show the data and let people decide for themselves... and 33% for three & outs is not really that bad when you score on 38% of your drives.... just about any coach will tell you that.
33% 3 and out is awful. I don't know of anyone that would accept that, especially against a schedule that features teams that aren't world-beaters defensively.
I considered taking a look at Alabama so far this year, but I decided against it because that comparison wouldn't necessarily be fair. So what about LSU? Looking at their record the past three years, and looking at Husker expectations, this seems to be a fair school to look at.
2010: 11-2 and missed a conference championship game
2011: 13-1 and lost a BCS championship game
2012: 10-3, no conference championship game, lost bowl game
34-6 and one BCS game over three years is pretty reasonable, even though they failed to make a conference championship game in two of those years.
So let's look at what LSU has done on offense. Rather than just 3 and outs, I decided to include any drives that lasted 3 plays OR LESS that didn't end in a score.
Against TCU, LSU had three such drives out of 12.
Against UAB, LSU had four such drives out of 13.
Against Kent St., LSU had zero such drives out of 10.
Against Auburn, LSU had four such drives out of 15.
Against Georgia, LSU had one such drive out of 11.
In five games, LSU has gone three and out (or worse) in 12 of 61 drives, or just under 20%. In their two games against ranked opponents (TCU & Georgia), they combined to go 3 and out only 4 times in 23 drives (17%).
Guys, this is not a particularly special LSU offense. They are good, but not great. They rank 37th in total offense (Nebraska is 21st). They average 42.8 ppg (Nebraska averages 43.3). They average 281.8 ypg throwing and 192.0 ypg rushing (Nebraska is 215.5 passing and 280.8 rushing). Their quarterback is in his second year as a starter (compared to 4 years for Martinez).
They are much more efficient with their offense, much more fluid. They don't have the herky-jerky look that Nebraska has with Matinez at the helm. I'm sorry, it's just not good when you are almost as likely to go three-and-out as you are to score on any given drive.
