I agree here. Smoove is not mature enough, or smart enough to put it bluntly to carry the label as "leader". That being said, I'm not sure JJ exhibits are the characteristics of other players we consider "leaders" of NBA teams. He's not vocal, he's subdued, and passive. Talent wise, JJ has the tools. It's the mental task of leading during TO's, at halftime - get in the faces of other players. Bibby has shown flashes, with his questioning of Woody and how he uses Smoove. I think Bibs is seeing that Joe isn't capable of being viewed as the team leader, and if he resigns, I bet we see a more assertive point guard next year.
