Utah Jazz
Like Phoenix, Utah never actually offered anything but according to Zach Lowe, Sam Presti had semi-serious conversations with the Utah Jazz.
Many different players were discussed in these conversations including Gordon Hayward, Derrick Favors, Alec Burks and Enes Kanter.
Ironically, Kanter (still) eventually ended up in Oklahoma City in a separate trade years later. However, Harden never set foot on the floor in Utah sporting a Jazz uniform.
