Zeke has been dealing with tendenitis issues and he's also getting double and tripled team.
The key to his success, however, lies in getting some of that interior pressure off of him. I don't think Dambrot gets enough consistency from his shooters to shift more of the responsibility to him, nor does he get consistency from Tree yet (emphasis on the YET) because he gets doubled a lot too. Ultimately, Zeke's success on offense will depend on which of those other elements is working best on any given night.
Just my analysis.
