If the Dallas Mavericks are going to make it out of the early-season pit they dug, it will require a lot more nights like Sunday. Two days after seeing a four-game win streak snapped in an overtime loss to Oklahoma City, Shawn Marion scored 20 points, and O.J. Mayo and Vince Carter added 15 apiece as the Mavericks fought off a late Orlando surge and beat the Magic 111-105 on Sunday night.
