The Lakers. They have Pau Gasol back, and expect no mercy from the Lakers, like the Clippers did. They will play hard for 4 quarters and not sure of Mavs can keep up. Artest/Odom will defend Nowitzki and will give him fits.
I took the Wiz on the ML so I like your chances with that, also took the Mavs +8. I did take the Pistons -5 though, that one might give you some trouble, but other than that, seems like a good play to me.
