RB/WR/TE Talent
Say what you will about FSU's recruiting, but they have done a solid job recruiting the running back, wide receiver, and tight end units over the past few years.
There's a lot of unproven talent on the roster, but that talent should be primed and ready to roll by the time O'Neal's ready to play. Almost all of the young guys are sophomores or younger, which means O'Neal would get to play with a bunch of juniors or seniors at the skill positions as a redshirt freshman.
Of course, this hinges on guys staying and not entering the transfer portal, but it works both ways. FSU coaches could bring some talent from the portal at those positions as they've done over the past few seasons.
If the offensive line has gotten to a serviceable level or better, if FSU struggles offensively, it won't be due to a lack of talent.
