Grade the Trades: Marks for all 3 of the Dallas Mavericks' offseason deals

1. Dallas Mavericks sign-and-trade for Grant Williams through a three-team trade with Boston and San Antonio

Now this was like the cherry on top for Maverick fans after those two trades that happened during the NBA Draft. The Boston Celtics, Dallas Mavericks, and the San Antonio Spurs were all involved in a three-team trade, where the Celtics sent Grant Williams to Dallas, and the Mavericks sent Reggie Bullock to the Spurs along with a pick swap. The Celtics and Mavs both acquired multiple second-round picks as part of the deal as well.

Bullock was a player on the Mavericks last year that didn't show up until December on the court and was set to receive $10 million in the final year of his contract next season. The Mavericks wanted to upgrade the forward position, and they did that by going out and getting Williams from Boston.

Williams played his college career at the University of Tennessee, where he was their small and power forward on the court. He averaged eight points and five rebounds a game last season with the Celtics. What I like about him is that he can play three positions on the court for the Mavericks.

As part of the sign and trade, Dallas signed him to a four-year, $54 million contract.

The reason why I give this trade an A- is the fact the Mavericks were able to shed Reggie Bullock's contract and was able to upgrade the forward position for a long time. The Mavericks were also able to pick up two second-round draft picks, which is turning into a significant trade piece these days.

Overall, Harrison has had a successful offseason upgrading this Mavericks roster without giving up significant key pieces such as Josh Green and Jaden Hardy. Kidd was right when he said fans would see a lot of new faces throughout the roster after last season. The moves Harrison made this offseason could set up the Mavericks for some deep playoff runs over the next couple of seasons.
