And you'll be overpaying due to his draft position. For 5-7 mins/per, I'd rather have a draft pick this season who will be developing on his rookie contract. I could care less about guys that are in the 10-15th spots on the roster, other than perhaps having a couple of vet-minimum guys who can step up if injuries happen (or rookie picks to do the same). Jimmer cannot be a part of a 3-wing rotation. He can't be the backup PG. Look at any mock and you can find at least 5 players at #21 who are much more likely to add value to the Jazz as backups at their respective positions.
SOrry should have included that I do not want the Jazz to trade for him. At most I'd be ok with them signing him once he is a free agent.
