Penn State would most certainly probably use him mostly as RB. If not exclusively.
Va Tech has Brent Pry (Franklin's former DC) as a it's new HC, and he brought Tyler Bowen with him from Penn State. Bowen was the co-OC and now OC at Va Tech.
They will also bring a brand of power football to the ACC. Or try to. And Seldon would end up at RB there too.
At Tennessee
With
Nico at QB
Bru McCoy, Hyatt, Calloway, M White, K Webb, Tate? at WR.
Wright, Williams, Sampson at RB
Seldon could comfortably contribute at BOTH and never have to be the main offensive weapon.
That'll be Nico Lamaleava...
Quite frankly: he'd have played with one of the best offenses in college football for 4 years, a bunch or spectacular highlights, and very little wear and tear...college degree in hand with the NFL drooling over him.
At least that's what I see.
But what do I know
