Mavericks reportedly add four-time champion Klay Thompson

The Mavericks couldn't make three-pointers in their Finals loss to the Celtics. Now, they've reportedly added the second-greatest three-point shooter in NBA playoff history.

Klay Thompson, who's made 501 three-pointers in his playoff career, is joining the defending Western Conference champions on a three-year, $50M contract, per ESPN's Adrian Wojnarowski.

A career 41.3% shooter who is sixth all-time in career threes, he immediately gives the Mavericks the best shooter they've had in the Luka Doncic era. Dallas got to see what he could do in the conference finals in 2022, when Thompson hit 15 triples in a 4-1 series win for the Warriors.

Dallas has reloaded this week, adding Naji Marshall in free agency and trading Tim Hardaway Jr. to Detroit for Quentin Grimes. The latter move, which cost the Mavericks three second-round picks, also opened up a $16.1M trade exception reportedly used in the sign-and-trade for Thompson.

They also sacrificed 23-year-old Josh Green to make the deal, sending him to the Charlotte Hornets.

Thompson should benefit by playing alongside Doncic and Kyrie Irving; they both draw lots of defensive attention and love finding teammates behind the arc.

He may be on the downside of his career, but Thompson still made the fourth-most three-pointers in the NBA last season. The former Warrior also clearly wants to play for a contender, reportedly turning down bigger and longer offers from other teams.

Dallas hadn't made the NBA Finals in 13 years before last season. Its aggressive moves shows it's anxious to get back next year, too.
