The biggest move that didn't happen at the 2025 NBA trade deadline was Kevin Durant's return to the Golden State Warriors.
For a night or so, it appeared the Phoenix Suns star was on the verge of being sent back to the team where he won two NBA championships in three years. The Warriors would have received Durant, the Phoenix Suns would have received Jimmy Butler from the Miami Heat and the Heat would have received some assorted assets.
The next morning, however, it was reported that Durant had no interest in going to Golden State, and the trade fell apart immediately.
