Offseason Report Card: Mavericks get three As, two Cs, and an F for summer moves

1. Mavericks trade for Grant Williams

The Dallas Mavericks completed a three-team trade with the Boston Celtics and San Antonio Spurs, sending out Reggie Bullock and a flurry of draft assets in exchange for 24-year-old forward Grant Williams.

Recent rumblings had indicated that the Mavericks were interested in Williams and Matisse Thybulle, and they found a way to make a run at both of them. But this deal for Williams was perfect.

Bullock was heading into the final year of his contract, so flipping him for any sort of value would have been a win for Dallas. But instead, they managed to turn him into four years of Williams, who is a better defender and three-point shooter at this point in his career.

Williams is a multi-positional defender who can guard some of the best bigs in the league while also getting out on the perimter and keeping up with guards. He will help the Mavericks reshape their defensive game.

Plus, he has been a 40% three-point shooter for the past two seasons, which will give Luka Doncic and Kyrie Irving a great target to kick out to on the perimter.

Williams inked a four-year, $54 million deal with Dallas, closing in at $13.5 million per season AAV. That's phenomenal value for a 3-and-D guy of Williams' caliber, especially under the new CBA that's being ushered in.

Turning draft capital and Bullock's expiring deal into Williams is as good as it gets for Dallas.
