This is what I was wanting to discuss, is the kicking game more or less important in a high scoring game as opposed to the old style play. For example, one TD is very, very valuable to Missouri because they averaged 13.6 points per game. One TD is 1/2 their score. One TD is not so valuable to Baylor because they averaged 48.1 points per game. One TD is 1/7 their score.
Back to kicking. I see your point, the higher the score the more kickoffs and kickoff returns there will be, therefore the more chances to mess up. But wouldn't that be true of every phase? The more I run the ball the more chances of a fumble. This is not so easy to figure out, is it, which is why I was wanting the discussion. The more PATs, the less punts and FGs. Hmmmm.
If I could find the special teams rankings for a the top four football teams in, say 1962, and compare them to 2015, that would answer my question.
