Mavs’ Grant Williams Sign & Trade Not Official; Could Dallas Expand to 5-Team Deal?

The Dallas Mavericks initially agreed to a three-team trade with the Bostons Celtics and San Antonio Spurs to acquire Grant Williams. If the Atlanta Hawks wants Toronto Raptors' Pascal Siakam, perhaps the Mavs can get Clint Capela in an expanded five-team trade.

The Dallas Mavericks had three big goals coming into this offseason: re-sign star point guard Kyrie Irving, add a starting-caliber center into the mix, and sign or trade for a 3-and-D wing. 

Despite rookie Dereck Lively II showing promise at the NBA Summer League in Las Vegas, Dallas’ starting center situation is still to be determined, but the Mavs accomplished their other two goals by re-signing Irving to a three-year, $126 million contract and agreeing to a three-team sign-and-trade for Boston Celtics’ defensive-minded wing Grant Williams.

That pending three-team deal involving the Mavs, Celtics and San Antonio Spurs was reported on Wednesday of last week, but it has yet to be made official. So, what could be the main reason for that?

It’s possible that the Mavs are trying to expand this deal to get more bang for their buck by adding another serviceable wing or big man. Here were the original three-team trade terms: Mavs receive Williams on a four-year, $54 million contract, and two second-round picks, the Spurs receive Reggie Bullock and a pick swap in 2030 (from Mavs), and the Celtics get multiple second-round picks.

Given the Mavs’ draft-night interest in Atlanta Hawks veteran center Clint Capela, and Atlanta's rumored interest in trading for Toronto Raptors All-Star forward Pascal Siakam, here's an expanded five-team trade that could make sense for all sides involved:

Mavs receive: Grant Williams, Clint Capela. Hawks receive: Pascal Siakam. Raptors receive: DeAndre Hunter, Tim Hardaway Jr., two first-round picks (from Hawks) and two second-round picks (from Mavs, rerouted from the original three-team sign-and-trade). Spurs receive: Reggie Bullock, 2030 pick swap (from Mavs). Celtics receive: two second-round picks, trade exception.

There are other ways this trade could evolve and include different teams than listed above, but this one makes some sense based on the Mavs' needs, as well as what the Hawks reportedly want from the Raptors. We'll find out soon if the Mavs' original three-team trade for Williams will be expanded, as we're approaching the one-week mark from when the initial deal was agreed upon.
