I really like DeAndre Jordan, and I wanted him on the Celtics because I think his defense and rebounding was exactly what we needed as a compliment to our other players. However - and I know he is a younger player - I don't know how much more of a difference Jordan has on the Mavs than what Tyson Chandler had on the Mavs. Other than that, they lost Monta Ellis who was a good (albeit inconsistent) scorer for them in exchange for Wes Matthews, who I really like, but that injury...
I don't know, I still don't think they make the playoffs in the west because they don't have a good PG rotation and there is not much talent coming off the bench there (which of course can change.)
