First off, I hate this trade. I wouldn't trade Harris for Kidd straight up. When we don't win the championship this year or next, 3 years from now we will regret this. Then losing Diop is idiotic as well, especially after the two big man acquisitions made by phoenix and LA.
The only thing that could possibly salvage it would be a move like acquiring kurt thomas. Don't know what pieces we have left to even make this work but it was discussed here sometime ago.
