Lowry is the EXACT type of PG they need though, especially Fultz. A PG who can show them the ropes (on both ends), provide a stable veteran presence to balance out the inexperience, and control the ball only when the team needs him to and not monopolize possessions (Lowry doesn't get enough recognition for his ability to balance when to handle the ball and play off it in relation to a team's needs - only Steph is better). I don't necessarily disagree with just allowing the core to develop on their own, but a PG in the mould of Lowry would most definitely NOT stunt Fultz's growth.
This argument is more or less futile anyway since it seems as though Lowry wants to be on a contender.
Nah they need a Jason Kidd
