Maybe. No doubt he was one of the best two players in the trade. To argue whether he would have started is probably pointless though. The question for me is why he didn't end up in Utah in the first place. Either DL didn't ask about him, which would make him inept, he asked but OKC didn't want to include him (they got Singler so maybe they were looking for a wing), or he was available but DL didn't want him. My premise is that the Jazz were, and are, fully committed to Exum as a 30-35 MPG guy. If that's true, I can see why they might not want Jackson. What would be the point? We weren't playing for anything and were trying to develop our PG of the future. Why muddy the waters with another PG who wasn't in our long term plans. Exum needed all the minutes he could get. That's why I don't think we would have started Jackson. Numberica could be right though that they would have started Jackson in place of Ingles or Hood. But who knows?

For me it's really the long view that's relevant, for the Jazz and Jackson. With Exum in place the Jazz would not want to commit big bucks to a backup PG, and Jackson would not want to sign on as Exum's backup. Maybe the Jazz underestimated him but he was averaging 28 MPG in OKC and putting up average numbers. Maybe we could have treated him as an asset, but you'd have to sign him first. If the Jazz didn't think they could re-sign him or that he would be a distraction then they were better off with the first round pick. OKC was in the exact same situation and punted. Should we have taken a flyer? Maybe, but I think Jackson would have walked for nothing and everyone would be complaining about it.
If that's true then the Jazz don't deserve any fans. Your 2 cents on this is asinine.
