Forward Shawn Marion will be the first to admit he didn't have a good performance in the Dallas Mavericks' Game 2 loss to the Oklahoma City Thunder. He made only 4 of 13 shots, some of them putbacks and layups. But Marion, a 12-year veteran who is hoping to make the most of what might be his final chance at a title, bounced back with a strong effort in leading the Mavericks to a 93-87 victory Saturday night in Game 3.
