Time to bump this thread.
I personally wouldn't want to see Kelly traded. I really think he has been really good in his role. Opposing teams' supporters would ovewhelmingly like to see Kelly on their teams based on how he has performed here. He brings such a combination of skills to Jazz that it will be very difficult to replace.
I know he doesn't fit Jazz's time line in longer run but to carry the team to first PO-experiences, I think Kelly should remain on this team. Without any further knowledge, I feel like he has a seriously positive vibe in the locker room also.
