Think on the bright side... Z will be back in a month. During the month of him out, the Cavs are still good enough to win most of our games, and it gives more minutes to JJ and Darnell, and Andy gets to start, which he has been very good at.
This is a GREAT time for JJ to prove that he deserves to be in the rotation. I remember when Boobie didn't get many minutes at the beginning of the year, but starting around this time in the season, he started to see some minutes (like 10 MPG) and he really made the most of them, and in the playoffs, he made the most of his minutes too, and started to get like 30 MPG, and really come up big for the Cavs.
