Acquiring Kyrie Irving would cost the Dallas Mavericks multiple pieces
Irving has multiple options, but he is not going to decline his $36.5 million player option to sign for the $6.3 million taxpayer mid-level exception. The Mavs do not cap space, so their only avenue to acquiring Kyrie would be via trade.
Assuming Irving opts-in and extends, Dallas would have to match his $36.5 million salary in a deal. Jalen Brunson likely will not be part of this trade because completing a sign-and-trade would hard cap the Nets (and Mavericks if it turns into a double sign-and-trade), and Brooklyn would not be eager to cut multiple pieces from their roster.
The Nets would want Dorian Finney-Smith, and the Mavericks would have to add in Tim Hardaway Jr. or Spencer Dinwiddie to make the math work. The deal could also cost Dallas Josh Green, and Brooklyn may try to pry away Reggie Bullock or Maxi Kleber with at least one first-round pick.
By the time the trade gets done, Dallas is left with Luka Doncic, Kyrie Irving, and not enough pieces to compete for a championship. The Mavericks would only have the taxpayer mid-level exception and minimum deals to hand out in free agency, and veterans may shy away from teaming with Kyrie because he struggles to stay on the floor.
The Mavericks should avoid acquiring Kyrie Irving this summer. They want a second star, but the 6’2 guard is not the answer for Dallas.
