Tyler Zeller has received most of Mozgov’s minutes since his role has gotten reduced, and that has been better for the team. Mozgov just never developed chemistry with the main rotation guys. There is no point playing him if he is not making an impact. The Nets, who are still in experimentation mode, have tried different lineups. However, being better compared to last year means Atkinson can coach and be more focused on winning instead of which combination works best. That is still a concern, but the pool of players to pick from is small. In recent weeks, Zeller has stepped up and worked his way into the rotation.
