I didn't see any football players during my high school years who ever made a name for themselves, since our teams stank pretty badly. There was one kid a few years after I had left, who did get a scholarship offer to play quarterback at Miami University (Ohio), back when they were everyone's doormat, and before Rose turned things around. He never really materialized as a player, though, and I suspect the scholarship was more in line with granting one of the university's bigwigs a family favor.
The only big star from my town was an amazing basketball player named Greg Simpson, who went on to play for tOSU until he got thrown in jail for the first of many, many times. Last I heard, he's a repeat loser felon.
Once I moved to Alabama, though, I've had the pleasure of seeing the two players in the title play in high school.
Nobody could cover Julio Jones in high school, since he was bigger, faster, and stronger than anyone else, not to mention, having some of the best hands and route running anywhere. I honestly believe he could have started for just about any college team even at the start of his junior year. I only got to see him on TV, where one of the local stations covered a couple of the Foley games, but dang, that guy was scary.
He was arguably scarier switching back and forth between rush and drop end on defense. Even though he was a lot slimmer than the blockers on offense, he could reach around anyone before they knew his hands were beyond them, and pull down a running back with ease. That plus with his freakish athleticism, he'd pretty much break your ankles if you were a blocker, trying to match his footwork.
Marlon Humphrey was much more local to me, though. He was guaranteed to shut down the top receiver on any high school, bar none, regardless of whether they were a blazingly fast receiver, a strong handed possession receiver, a precise route runner, etc. He could cover them all during his high school days, and the only thing that surprised me was that he wasn't starting as a true freshman.
Even before they started excelling in college, it wasn't surprising at all that both of them became superstars on Nick Saban's Crimson Tide teams.
