UPDATE: BI Likely to be Traded[Pel's Media expect a big push to move in Ingram in Early August]

That's nice and all. However, would BI accept a team friendly extension? If so, we are probably not having these discussions. Does BI and Zion work?
What leverage does he have not to? I mean he will certainly be valued higher around the league than many on in the local twitterverse thinks. But he simply didn't play well enough to make such demands.

Yes they work. It requires Zion making a leap in his skill level like BI did over the last 3 years. Zion has been mostly stagnant.
