New Mavericks wing shows leadership through heated post-practice speech

One of the Dallas Mavericks' best moves of the offseason was trading for Grant Williams.

It was a three-team trade with the Boston Celtics and San Antonio Spurs, and the Mavs only had to give up Reggie Bullock and a first-round pick swap. Dallas also acquired two second-round picks as part of this deal.

This deal was a bargain, as they didn't give up much, and it also didn't allow Williams to hit the free agent market.

Dallas hasn't had the best luck during free agency in recent history, and rather than signing Williams and risking Boston matching their offer, they acquired him through a sign and trade.

Williams has already been confirmed as the third guaranteed starter next to Luka Doncic and Kyrie Irving by Mavs head coach Jason Kidd, and he is already showing great leadership among his teammates.

Dallas is often plagued by slow starts to the season, and Williams doesn't want to let that happen again. Williams also knows what it takes to make deep playoff runs and has played in 61 playoff games in just four years.

Williams has the playoff experience that Dallas needs, and he knows the importance of training hard from the start.

After Dallas' practice on September 30, one player emerged from the rest and led a heated speech about this. That player was Williams. Here's what he had to say to his teammates.

"Hold each other accountable," Williams said. "We can't come in sloppy. The only way you win in this league is if you take it every single night. You can’t wait til the (expletive) playoffs, you got to do that (expletive) every (expletive) game.”

Williams has only been with the team for a short amount of time, and he is already showing great leadership. The Mavs needed someone with this kind of personality, and Williams isn't afraid to push his teammates and tell them how it is.

Mavs fans' first chance to watch Williams will be on October 5 in a preseason game against the Minnesota Timberwolves.
