Again, they turned the defense around the last two season in the regular season.
But ok. Continue.
It is cause for concern.
I would note this. Bogut, JR, and Love are three solid defenders. All coming back.
I do think that in the two previous seasons, we had less injuries and roster turnover late in the year.
In 2015 all three of our additions(Moz, JR, Shump) were added in early Jan.
Last year, the only significant second half of the season roster change or injury was the addition of Frye.
This year we lost JR, added Korver, lost Love, added Williams, added DWill, still have to add Bogut and back in JR/Love.
That's a lot of roster change and rotation change.
However, even with that flux in personally and rotations, the players on the floor are in control of their effort and communication on D, so that does need to improve no matter what else is going on.
But I do think it's significant that we're giving major rotation minutes to a guy who's been with the team three weeks and another guy who's been here five days.
So ever the optimist that I am, I do think there are valid reason to be concerned but valid reasons to support the idea that the defense will improve as the roster gets complete and settled.
