Richard Hamilton has been around long enough to know how it works. He spent the 12 hours leading up to the game Saturday night against the New Orleans Hornets reading "Old Man River'' text messages on his phone. "Yeah, that was funny,'' Hamilton, 34, said with a laugh. During the third quarter of the 115-86 victory Friday over the Cleveland Cavaliers, Hamilton was in need of a jump-start, and a Cavs fan obliged, calling him "Old Man River'' after Hamilton had scored only three points in the first half.
