Power 5 kickers / kicking has always been an enigma for me... It's like there are 64ish spots for kick off & FG/PAT. With the number of high school boys in the USA you'd think every single P5 team could have an excellent kicker every single year. My HS team used a kid from the soccer team. He did three things all practice; practiced kick-offs, FGs, and PATs.
Why aren't they all great?
Another factor is that it's easier to kick in high school than college. In HS, you're allowed to use a tee for field goals and PAT's ... not in college. Also, the uprights are nearly 5 feet wider in HS. I would imagine there are a lot of HS kids who look like pretty good kickers until they try kicking under college rules.
