Agreed, they've gone as far as they could with Iguodala, they need to find a way to get a consistent scorer.
I don't see the grizzlies doing it. The 8th pick in the draft doesn't get you Thomas Robinson and it remains to be seen what would be left on the board. Ed Davis is an okay player, Calderon is decent but old and his contract is 10 million. If I'm the grizzlies I'd take Amir Johnson over Davis anyway.
