Mavs part from piece below (this is a fantasy trade proposal from Toronto guy and Cato's opinion):
To Mavericks: VanVleet
To Raptors: Josh Green (two years, $7.86 million), Davis Bertans (three years, $49 million, including player option for 2024-25) and a 2025 first-round pick
The Mavericks’ view: Dallas isn’t expected to trade first-round picks or a young player like Green in any situation this season; the front office understands its ammunition needs to be saved for a major move in the next year or two. This isn’t the sort of deal that would tempt them. VanVleet would help the Mavericks, but he doesn’t fit their timeline and doesn’t offer the defensive upgrade they’re wanting for their 23rd-ranked defence, per NBA.com. — Tim Cato
