There are a couple of options I think might entice the Suns to make a trade
1st taking on the contract of Brandon Knight 2 more years of about 30 million. (huge risk because of knee injury)
2nd Draft picks. Jazz would have to gamble that in the future they are a strong play off team and offer a potential protected pick
3rd Young talent
Looking at their depth chart you have
PG - Ulis, Knight, Canaan (pretty week unless knight becomes good over night)
SG - Booker, Daniel, Reed (other then booker this spot falls flat also)
SF - TJ Warren, Josh Jackson (this spot is actually decently solid)
PF - Chris, Bender, Dudley, Peters (This spot has A LOT of youth but Chriss and Bender have seriously Under performed)
C - Chandler, Len, Williams (Age is not chandlers friend and Len is way under performing)
* I don't see them being interested in Hood because you don't want to get him just to back up Booker and there aren't any minutes at the SF
* Favors actually makes a lot of sense to their franchise and would be a great addition next to Chriss but does his age fit with their youth movement
* I could see them have some interest in Rubio because he would be a great transitional player
* Dante Exum might be the player they would covet the most.
So it would depend on what the Suns are looking for and would the Jazz be willing to take Knights Salary to get Bender that is probably the solution that makes most sense
Something along the lines of Favor, Rubio and Bradley for Knight, Bender and Dudley. (a third team might make it easier) I personally think the Jazz are giving up to much. for 2 longer contracts and an under performing prospect.
