Saying that he wants to stay in the Utah Jazz is just all about words and if that's what really desires to be but with his market value and if it can't be helped then, he'll for sure going to find another team that's willing to give his desired contract not unless he's got the heart to stay for Jazz.
People are even rooting for the Utah Jazz already to participate in the upcoming playoffs because despite of the fact that the team is still rebuilding, they are showing some good signs from having a consistent performance since the season started and still getting some improvement in every games which is quite unexpected from a team that is supposed to be tanking this season. Hopefully, the Jazz can adjust with Clarkson's price for at least a year to see where will this team go.
Still, he has became the franchise player of Utah Jazz so if the management is considering that. They'll have to bear and give the demand of JC if it's still allowable by their budget and limitations.
