Adrian Wojnarowski of Yahoo Sports broke the news on July 13 and then reported that Jefferson's deal was of the veteran minimum variety for one year:
Tim MacMahon of ESPNDallas.com analyzed Jefferson's signing in the context of how it relates to Chandler Parsons:
The Mavs also lost Vince Carter on the wing to the Memphis Grizzlies, something MacMahon also addressed:
Carter had something of a career renaissance this last season, so it makes the acquisition of Jefferson all the more crucial for Dallas to keep pace in a highly competitive Western Conference.
Jeff Caplan of NBA.com highlighted how valuable Jefferson could prove to be with a capable cast of stars flanking him:
There's quite the fluctuation of players transpiring in the West, as Parsons may still go to Dallas after the Rockets landed former Washington Wizard Trevor Ariza, per Wojnarowski:
This appears to be an ideal fit for both sides. Jefferson said as far back as December 2013 that he was keen on competing for the Larry O'Brien Trophy, per the Deseret News' Jody Genessy:
If I get an opportunity to play for a championship team, I'm going to go hunting for them. I have no loyalty. I'm not one of those guys that plays for the same team for 15 years like a Reggie Miller that has to decide whether or not he's going to go do that. No, I'm a gun for hire.
Although Jefferson, 34, adds to the advanced age on the Mavs roster, the current core of players harnessed their experience in an exceptional way in the most recent playoffs. Dallas pushed the eventual NBA champion San Antonio Spurs to seven games in the opening round. There is reason to believe the Mavs could go even farther even with face of the franchise Dirk Nowitzki in the twilight of his career.
A retooled roster now features an upgrade at center. Through a trade with the New York Knicks, Tyson Chandler returns to the team he helped guide to an NBA title in 2011. The front line is longer in the tooth, loaded with 30-somethings, but Jefferson is a key addition to the Mavs as far as depth is concerned.
With how well Jefferson played as a member of the Utah Jazz in 2013-14, scoring 10.1 points per game, there's a chance he'll fare even better with a superior squad in Dallas.
