If you want touchbacks, Cody Parkey from Auburn is my favorite kid. I was at the game when they played Tennessee and he kicked two kickoffs through the uprights. Here's some video:
Also, he had over 70% of his kickoffs result in touchbacks this season at Auburn, per www.cfbstats.com.
I would rather have a veteran kicker, but this guy started everyone at the 20 this season.
