Mavs are so deep and talented right now. I've actually had a problem with most of their guys on their roster at one point in time (obvious hatred for Kidd for a while, never really liked Dirk until recently, thought Butler was overrated early in his career, Marion and his primadonna years in Pheonix, and felt Haywood was soft inside), but i've done a 180 on basically all of those guys.
Jason Kidd has really suprised me the past 2 years, he's having a rebirth at the point. Now they have 3 solid point guards, a plethora of 2-guards with Butler, Stevenson, Terry, and Wafer. A lot of flexibility at the forward positions with Dirk, Butler, Marion, and Najera all capable of playing the 3 or 4. And finally a not-great-but-very-solid roation of Haywood/Dampier at the C position.
Only question i have for the Mavs is what will they do come playoff time? most teams decide to consolidate their rotation, but Dallas has seemingly ~11 guys who rightfully deserve playoff minutes.
