​Several NBA contracts have flown under the radar because they’re just seen as players getting what they’ve earned. But one contract in particular, Gary Trent Jr.’s four-year, $64 million agreement with the Milwaukee Bucks, is under intense scrutiny.At first, it was the fans making noise about Trent being, as some might argue, overpaid. Now, the NBA is doing a double-take too. Officially, the NBA is conducting an investigation into the Trent contract, and now we know what piqued their interest.AdvertisementAdvertisementAdvertisementRole players, unless they’re really good at their job, typically don’t sign contracts worth $16 million per season. If they do, it’s likely not for four years. Yet, that’s the situation the NBA is looking at with Trent Jr.This isn’t the first time a team has backed up the Brinks truck to secure their target. What’s the real reason the Bucks are under league investigation?ESPN’s NBA insider Brian Windhorst revealed exactly why the league has taken up an issue with Trent’s contract this summer. It’s not just the monetary value; it’s the length too.AdvertisementAdvertisementAdvertisement“All four years are fully guaranteed,” Windhorst said. “That is a big part of this too. It’s not just the per-year, it’s the four years guaranteed. If you look at other contracts this summer, that’s not what was happening in the market for role players. Players like Donovan Mitchell, Victor Wembanyama — they got four-plus years guaranteed, not role players.”It’s not even just that a role player got an unusual contract; Windhorst later revealed the real red flag here.“The other thing is, he made $6 million over the last two years combined,” Windhorst noted.“That’s perceived by the league to have been under market value. The Bucks got Trent on discount. If a player wants to play on a discount, it happens every year; that’s not unusual. What raised the flag was that he would be overpaid by the same team he was underpaid for the past two years.”AdvertisementAdvertisementAdvertisementMaybe the Bucks thought no one would notice. Maybe they felt like Trent suddenly brought some near otherworldly value to the locker room despite seeing his on-court numbers drop across the board. Despite a situation that appears to be littered with red flags, Windhorst essentially says good luck proving any wrongdoing.“Now, proving anything here would be difficult,” Windhorst opined. “You would need some sort of paper trail documentation, and the league may not be able to find anything on it.”While the NBA community may be wondering what the heck the Bucks are doing up there in Milwaukee, there may not be anything that the league can do about it. Meanwhile, Trent Jr. can now laugh a little louder all the way to the bank. Or a few of them at that rate.
