If the Jazz are keyed in on Fears, I don't think they risk trading back to #8. Jazz are probably thinking Tre/Kon/Fears in some order at this point.
1- Flagg
2- Harper
3- Edgecombe
4- Johnson
5- With Johnson gone, Jazz trade back, Pels take Ace
6- Fears/Knueppel
7- Fears/Knueppel
8- ???
I like Essengue as much as anyone, but his lack of on-ball creation in the half-court stifles his star potential at this stage. (You can make an argument that Fears has some star potential because he's dynamic with the ball.)
