I did some research as to FGs and XPs, mainly because of Nebraska's struggles, but then also Alabama's. Because even though they can win games and titles, they have difficulties with kickers. Since Nick Saban went to Alabama he hasn't had one kicker attempt either all fgs or all xps.
Saban's teams have missed over 100 fgs, 250/350 since 2007. They have missed 24 xps.
Nebraska over that same time-frame is 207/257 which is 9 % points better than Alabama. We have missed 10 xps.
So what does this mean? You need a damn kicker. But you can still overcome kicking woes to an extent. Also Nebraska's worst fg% was this year during that time span. Coincidentally this is the 6th time Alabama has finished under 70%.
