I went back and forth on Kidd over the last couple of years.
I underestimated the number of 3PM from Kidd. Getting almost 200 from a 1 pt usage guy who also solves your passing needs is really nice. I used to think Nash was better because of the scoring/near 60 eFG%, but Kidd wins out on account of threes, defense and DReb%.
He's also a very nice fit with Kareem, who excels on O boards but not so much on D boards.
