Zeller already has strong ties to one current Buck from their days together in college, and interim head coach Joe Prunty from a previous coaching stop - more on both of those things shortly - which may help him to settle in with his new teammates a little quicker.
The Nets were primarily concerned with acquiring at least a second-round pick for Zeller; Vaughn's expiring contract simply made the money work, according to ESPN.
The only question remaining for both teams is if they will make more moves from now to the trade deadline, which is this Thursday.More news: China is blocking foreign cryptocurrency trading platforms

In Milwaukee, big man John Henson doesn't offer the Bucks enough. Let's assume the minutes go up for Zeller moving forward.
Vaughn has averaged 3.1 points in 133 games since being taken by the Bucks with the No. 17 pick in the 2015 draft.
Since the Nets are in the midst of a rebuild, Atkinson and the organization will likely give Vaughn a chance to see extended minutes at some point in the season. His best year as a pro came in 2014-15, when he averaged 10.2 points and 5.7 rebounds while appearing in all 82 games and making 59 starts for Boston.
For Brooklyn, they got what they wanted out of Zeller, which is a protected second-round pick via Phoenix Suns from the Eric Bledsoe trade earlier in the season.
