No. The odds of picking 1,2,3,5,or I think even 6
are higher than staying in the four spot. The only way the Jazz stay in the four spot is if Milwaukee, Philadelphia, and Orlando all win a top three spot in some order. If anybody outside of the top three move up to the top three then the Jazz will not draft 4th.
But you are right. Staying in the four spot is much more likely than picking 30th.
