And to thavoice's comment on a QB's impact on a High School game...........I totally agree. An elite running QB that can throw decent has a greater impact on a HS football game than an elite passing quarterback who doesn't run much. The former requires a lot less help from his teammates and is a lot harder for a defense to scheme to stop.
At BHS we had Dezmin Lyburtus in 2017. Dezmin, while not offered by any Division 1 schools (had a great career at WR for Ferris St. and Ashland), had a very similar impact as Tavien St. Clair.
It's just a different skill set, but colleges at the P5 level rely an extreme amount on metrics. They know that their players almost always (always an exception) need to lie in a certain skill set to rise to the level they need. Regardless of how Tavien's OSU career plays out, he blows their metrics out of the water. Those are their staffs words not mine. Oh, and that of Nick Saban as well, so take it for what it's worth.
