Following his agreement to part ways with the Nets, Deron found himself back on the open market, truly for the first time in his career. This time it didn’t take long to decide he wanted to head home to Dallas.
On July 14, 2015, Deron Williams decided to return home by signing with the Dallas Mavericks in free agency. D-Will made his debut against the Phoenix Suns and notched 12 points and seven assist in a 111-95 win. About a month later, he began to settle in and find some chemistry with his new teammates, posting a then season-high 30 points in an overtime victory over the Portland Trail Blazers.
Being back home in Dallas was nice for Deron because he was close to family and friends and he was able to play a bigger role on the court with the Mavericks.
“Being home in Dallas, it’s been great for myself and my family. I’m definitely enjoying it. I enjoy playing with these guys. It’s a great group,” Williams said. “It’s loose. It’s fun. I have the ball in my hands a lot more. I have a better rhythm here. Those things all contribute to better confidence out there.”
Perhaps his best outing for the Mavericks came in March of his first season with the team, when D-Will posted season-highs in points and assists. He tore up the Blazers again in yet another overtime victory to the tune of 31 points and 16 assists, becoming the first Maverick with 30 points and 15 assists since Jason Kidd in 1996.
An abdominal strain hampered Williams down the stretch of his first season, and it forced him to exit Game 4 of their first-round playoff series against the Oklahoma City Thunder and miss the remainder of the series.
That offseason, he re-signed with Dallas after a successful first season with the team, and he kicked off his second year in Dallas by scoring a team-high 25 points in the season opener against the Indiana Pacers.
In January 2017, Williams surpassed Kevin Johnson for 20th on the NBA’s all-time assists list after dishing out eight assists against the Los Angeles Lakers. Then after a few more nagging injuries, Williams was waived by the Mavericks in February 2017, allowing him to sign with the Cleveland Cavaliers.
