Giving up a game-winning TD drive with less than a minute to go is poor play, not luck.
Being unable to pressure a QB playing behind four inexperienced OL is not bad luck.
I'm sure we had plays go against us that shouldn't have in 2011, just as we had plays go for us that shouldn't have in 2012.
In 2011, ND didn't finish with 11 wins because they played poorly overall and lacked leadership both on the field and on the sidelines. In 2012, ND finished with 12 wins because they played well overall and had leadership both on the field and on the sidelines. Luck may have factored in to both, but that doesn't make it a prime determinant.
