2. Grant Williams
One of the Mavericks' biggest offseason moves was a sign-and-trade move that brought in Grant Williams from the Boston Celtics on a four-year, $53 million contract.
Williams carries a cap hit of $12.4 million in 2023-24 and it's hard not to love that number — especially when he was reportedly seeking $20 million annually back in February.
He's a versatile 6-foot-6 forward who can guard multiple positions and just shot 39.5% from the three-point line. While he "only" averaged 8.1 points and 4.6 rebounds over 79 games, his averages for each category have increased in each of the last four seasons.
He's also only started in 20.1% of his 288 career games, meaning an expended opportunity in Dallas should lead to those numbers jumping up even more.
Williams also brings invaluable playoff experience to the table. Despite only being 24 years old, the former Tennessee Volunteer has already played 61 playoff games, which includes four appearances in the 2021-22 NBA Finals.
That's not even to mention how his off-court personality made him an instant fan favorite in Boston. Although GMs shouldn't pay millions for "good vibes," building a strong locker room is key to winning titles.
So unless his numbers plateau or he creates unnecessary drama, Williams provides more than enough value to justify his contract.
