Interesting is that you have a father and son duo. Both All-Americans, so about as similar as one can hope for in comparison.
Now note that Van kicked off a tee while his son and virtually all the rest kicked off the ground.
I wonder where there records would be if the tee remained. If we assume that the tee aids them significantly, which these numbers imply, then that no-tee rule change could have altered (or actually maintained) the nature of the field goal and its impact on the game.
