Zeller fell shy of the playing time he first received upon landing with the Boston Celtics, netting only eight starts in the last two seasons, after being the starter in 59 of 82 games played in 2014-15.
The 7-footer can prove a decent perimeter mid-range shooter and rebounder for a team like the Nets who lost their cornerstone player in Brook Lopez after trading him to the Los Angeles Lakers for D'Angelo Russell.
Zeller last averaged 3.5 points and 2.4 rebounds per game in 10.3 minutes per game in a loaded Celtics team. His welcome in Brooklyn should come first and foremost with ample minutes at the position, only competing with Timofey Mozgov, Quincy Acy, and rookie Jarrett Allen.
During his best season in 2014-15, the North Carolina product averaged 10.2 points and 5.7 rebounds per game while shooting 55 percent from the field and 82 percent from the foul line.
