Zack aint that bad, I mean he's really putting up a double double with big minutes or not, he's not the best passer but besides Stephon who is. Lee is very fundamental, He will never be a star, but he'll always be good.
If Zack didnt turn it over so much and was much better defensively then i dont think there would be many people out there who wouldnt like him on the team and so on but he isnt getting it done. Stats wise it does look good i admit. Hopefully he can get a bit fitter and work on his defense and yeah all will be good with him.
