Quite honestly: What makes you think that Burke won't be it? I'm curious to hear your insight.
I'm not sure having your PG as your no.1 option is effective for a contending team. Can you think of any such examples? Maybe a big PG like Magic or Westbrook, but someone with Burke's size and skill set? He seems to have amazing ball handle, and he can really split the defense for a lay up or a push out for an open team mate. But if the team does not have a legit scorer (I don't think Hayward can play as well he did tonight on consistent basis), then teams will just collapse the defense on him and have other Jazzers beat them. I love Burke, and I see him eventually becoming our Parker. Hayward is our Ginobili. But we still need our Duncan.
