Jones and the words arguably and borderline should never be mentioned in the same sentence as starting PG. Not currently, not potentially, etc.
He's a fringe rotation player who's ceiling is full-fledged rotation player.
That's one of the problems with this board though. Largely due to the success of Parker and S bag (Ginobili was mostly developed when he arrived, Murray isn't a full-fledged star and Johnson isn't even under consideration, at least yet), many have this idea that virtually every 1st round pick is either destined for or has star potential.
Sochan's draft position is irrelevant in this case. His archetype doesn't have a star ceiling.
