The Mavericks called Thomas on Wednesday morning as he was grocery shopping near his home in Seattle. Thomas booked a flight to Sacramento and arrived a few hours before tipoff. 

Isaiah Thomas has agreed to a 10-day hardship deal with the Dallas Mavericks.

The Dallas Mavericks are planning to sign wing Charlie Brown to a 10-Day hardship contract. Brown will be the Mavs fourth hardship player.

Dallas has Reggie Bullock, Tim Hardaway Jr, Josh Green and Maxi Kleber in the NBA's health and safety protocols. In their absence, the Mavericks have added Marquese Chriss and Theo Pinson. The team plans to add Brown and George King to that mix in the coming days.

Brown has previously played for the Atlanta Hawks and Oklahoma City Thunder. This season, Brown has been playing for the Delaware Blue Coats of the G League. In 11 games, Brown has averaged 16.8 points and 8.1 rebounds per game.

The Dallas Mavericks have Marquese Chriss to a 10-day contract under the COVID-related hardship allowance.

Chriss (6-9, 240) holds career averages of 8.0 points (45.5% FG, 28.9% 3-PT, 66.7% FT), 4.9 rebounds, 1.1 assists and 19.3 minutes in 258 games (147 starts) with Phoenix, Houston, Cleveland and Golden State. He averaged 6.5 points and 6.5 rebounds in two games for Golden State in 2020-21 before suffering a season-ending injury to his right leg.

In 12 G League games this season, Pinson has averaged 16.4 points, 4.6 rebounds and 4.3 assists. 

When the Dallas Mavericks first entered the 2021 offseason, the plan was for Rick Carlisle to remain as head coach for the 21-22 season.

Carlisle had intended to travel to Slovenia in the summer to observe the national team's camp and spend time with Luka Doncic. Those plans were canceled at Doncic's request as he wanted no distractions.

Carlisle broached the subject of an extension with Mark Cuban, but was shot down. Carlisle still had two years remaining on his contract and the response from Cuban suggested his job status was uncertain.

Carlisle stepped down later that week and eventually was hired by the Indiana Pacers.

Doncic never called for Carlisle to be fired. 

Rick Carlisle wanted the Dallas Mavericks to select Donovan Mitchell in the 2017 draft instead of Dennis Smith. Tim MacMahon of ESPN writes that Carlisle "completely soured on Smith midway through his rookie campaign."

The treatment by Carlisle of Smith contributed to eventual issues with Luka Doncic. During Doncic's rookie season, he became friends with Smith. Smith showed Doncic around Dallas, lived int he same apartment building and had spent hours playing video games together.

While the Mavericks marketed their new guard tandem, Carlisle and the front office knew they would eventually trade Smith. The Mavericks eventually traded Smith to the New York Knicks in the Kristaps Porzingis trade.

"Carlisle's apparent determination to make Smith miserable during their brief time as teammates was appalling to Doncic," writes MacMahon based on the accounts of multiple sources. 

Carlisle even accused Smith of being jealous of Doncic during a team meeting. Doncic resented what he perceived as an attempt from Carlisle to pit him against his friend. The situation was an origin story for the mistrust and tension Doncic had with Carlisle. 

"It wasn't really about how Rick treated Luka," a Mavs player on the 2018-19 team said. "Luka hated how Rick treated other people."
