The same people who blame many of ND's losses on "bad luck" also have to accept that there was approximately the same number of wins in 2012 that can be associated with good luck.
That line is a 2-way street. I was shouted down a time or 2 for thinking that ND was very easily a 10-11 win team in 2011. This whole idea of luck can't be a one-way street such that we can only use "luck" to critically evaluate (or even denigrate) the football program, because very few were willing to grant 2011 as a potentially better season than 8 wins.
I am willing to say that ND played like a 10-11 win team in 2012. But that holds true for 2011, too. But many pointed to 2-straight 8 wins seasons as an indictment against Kelly.
