Imagine how good Hayward would be if he is the #2 option. Or #3. Imagine Exum and Favors running the pick and roll. And if that doesn't work, imagine posting Favors up with Exum cutting to the rim.
Then, life is easy for Hayward. Then, he is the third option and probably the best third option in the NBA.
That is what the Jazz envision for Hayward.
Could you imagine Favors, Lyles, Hayward, Hood and Exum on the floor?
That is 3-4 players who can shoot the three. Lyles out at the three point line spreading the floor. Exum and Favors running the pick and roll. If that doesn't pan out, kick it out to Hood, who can then run the pick and roll with Lyles. If that doesn't work, then drop it off to Hayward who can make play happen one on one....or Hood...or Exum.
The key to all of this is Exum. If he pans out, the Jazz are set. If not, then the whole thing is screwed.
