Pretty interesting stuff. Darko was brought up but I think there are a couple reasons why comparing JV to Darko is flawed.

1/Darko was drafted by a successful team that had no time to develop him, JV will get more coaching, and more game time minutes to figure things out.

2/ Darko may have been a much better player overall at this age but JV's NBA transferable skills are what matter.

3/ I like Detroit a lot, but as someone who immigrated as a young adult, Toronto is a way better place to find home away from home with so many cultural communities. I can't imagine the culture shock of Detroit being your introduction to North America. That had to effect Darko's developing game.
