Zach is not the answer, but he is a better all-around player then Frye and we shed Francis who is done.
That's all the trade is about. Frye will never be a 20-10 man in this league.
If Q is healthy and playing the 2, our perimeter D gets better. Stephon really stepped up his perimeter D when he was healthy in the middle of last season.
Balkman can play D, and JJ SHOULD be able to. Collins can play some D at back-up point.
That leaves Crawford/Curry/Randolph. If there is one thing that would change this team defensively, is if Eddy Curry got in good shape and made an effort on the defensive end.
I'm not asking for Alonzo Mourning, but perhaps at least Jermaine O'Neal.
The other big problem is turnovers, and here too, Curry needs to work on his low post IQ, to reduce the number of turnovers.
