I was a bit surprised, that we let Brooks go. I guess there was a deal with the Nets before draft night, that Danny couldn't back out of.
That said, I think it is hindsight to say that we needed backup wing players. Around draft time, we thought we had Green and probably Delonte coming back (that was the plan) and Big Baby leaving for greener pastures. Furthermore we had only JO at the center (and no reasonto believe that he will stay healthy), so it made a lot of sense to get a capable big man in stead of a shooter with attitude.
I'm not saying it was the right choice, but neither am I saying it was the wrong choice. For me the jury will be out until at least some time next season.
