The longest-tenured Net is no longer a Net.

Brooklyn traded Joe Harris to Detroit on Friday afternoon, along with future two second-round picks.

The Nets will send the Pistons a 2027 second-round pick (from Dallas in the Kyrie Irving deal) and a 2029 second-rounder (from Milwaukee in the Jae Crowder swap).

The news was first reported by ESPN, and confirmed by the Post.

Brooklyn got “minimum considerations” but created “massive flexibility this season” according to a source.

The Nets are now under the cap for the first time since 2019, when they added Kevin Durant and Kyrie Irving.

General manager Sean Marks picked Harris up off waivers in the summer of 2016, and he hadn’t played anywhere else since.

Harris – who turns 32 in September – led the league in 3-point shooting twice and became one of the best floor-spacers in the game; but multiple ankle surgeries and his body breaking down hurt his mobility and overall play the past two seasons.

Harris was going to be on an expiring contract for $19,928,571 this upcoming season.

As such, the Nets will create a $19.9 million Traded Player Exception – and with $100,000 in wiggle room, the TPE will be worth $20 million.

Brooklyn already had a huge $18.1 million TPE, as well as smaller ones for $4.5 million and $2.6 million.

They cannot be combined, although the huge one is good for a year, meaning it could be used at the opening of 2024 free agency.

The move could also encourage Brooklyn to use the full Mid-Level Exception of over $12 million, and the Bi-annual Exception which is $4.4 million.
