Ranking every move of the Dallas Mavericks' offseason so far

4. Sign and trade for Grant Williams

One sign of an excellent Mavericks offseason is the fact that the sign and trade for Grant Williams is the fourth-best move of the offseason. This move could have been a spot or two higher, but fourth seems like a good spot.

In this deal, the Mavericks gave up Reggie Bullock and an unprotected pick swap in 2030, but they got Williams and two second-round picks in return. Dallas gaining multiple seconds in this deal was crucial, as they were desperate to land some.

Williams brings much-needed physicality and intensity on defense and will likely start at power forward for the Mavs.

Last season for Boston, Williams averaged 8.1 points, 4.6 rebounds, and 1.7 assists per game and shot 39.5 percent from three. He will be a great floor spacer to add to the mix and give Dallas some more defensive versatility.

Another thing about Williams that makes this deal even better is his playoff experience. Williams has played in 61 playoff games during his career and has started in five. He also has experience playing in the NBA Finals.

Losing Bullock in this trade could hurt more than expected, as Dallas is thin when it comes to defensive-minded guards, but Williams' overall defense should help relieve some pressure off the Dallas guards.
