The Mavericks have intensified their efforts to open up room below a second-apron hard cap to sign free agent guard Dante Exum, according to NBA insiders Marc Stein and Jake Fischer, who report (via Twitter) that those efforts have centered around finding a new home via trade for forward Olivier-Maxence Prosper.
Dallas reached an agreement to re-sign Exum to a one-year deal way back in July 2, but the transaction still hasn’t been officially finalized. That’s because the Mavericks’ team salary for apron purposes currently sits at approximately $206.2MM, which is about $1.6MM below the second tax apron ($207,824,000).
The Mavs hard-capped themselves at the second apron by using the taxpayer mid-level exception to sign D’Angelo Russell last month. That means their team salary can’t surpass $207,824,000 at any point for the rest of the 2025/26 league year. A minimum-salary deal for Exum would carry a $2,296,274 cap hit.
With training camps still over a month from getting underway, there has been little urgency for the Mavs to resolve the apron crunch to this point. However, it sounds as if they’re ramping up their attempts to find a solution, and trading Prosper has long been considered a path they’ll explore.
The 24th overall pick in the 2023 draft, Prosper has played a very limited role during his first two years in Dallas, averaging 3.5 points and 2.2 rebounds in 10.0 minutes per game across 92 regular season outings, with a .396/.260/.658 shooting line. Given that he’s buried on the depth chart and isn’t owed any guaranteed money beyond his $3MM salary for 2025/26 (his deal includes a $5.3MM rookie scale team option for ’26/27), the 23-year-old is the team’s most obvious trade candidate to make room for Exum.
Dallas has the ability to send out up to nearly $8MM in cash in a trade, which would more than cover Prosper’s 2025/26 salary, but potential trade partners will likely be seeking a second-round draft pick in order to take on that $3MM cap hit. The most recent trade completed this summer, for example, saw the Heat send a future second-rounder to the Nets along with Haywood Highsmith and his $5.6MM expiring salary in order to get below the tax.
The Mavs only have two tradable second-round picks: Philadelphia’s 2030 selection and their own 2032 second-rounder. If they don’t want to give up any draft equity and can’t find a trade partner willing to accept cash, waiving and stretching Prosper’s $3MM salary would be an option, though it would have to be done by this Friday to ensure he clears waivers on August 31. That would spread his cap hit across three seasons at approximately $1MM per year, opening up an extra $2MM in room below the 2025/26 second apron.
The Mavs are currently carrying 15 players on guaranteed or partially guaranteed contracts for ’25/26, so moving off Prosper (or another player) is also necessary to open up a spot for Exum on their projected 15-man regular season roster.
According to the Cavs, Strus is expected to resume basketball activities in approximately three to four months. That means he’ll be sidelined for the start of the regular season, which will tip off in less than two months.
Tonje, 24, spent four seasons at Colorado State, then transferred to Missouri in 2023 for his super-senior season, but was limited to eight appearances due to a season-ending foot injury. He was granted a medical redshirt and made the most of his final year of college eligibility with a breakout season at Wisconsin in 2024/25.
