’s Ian Thompson reports: Rudy Gay, Memphis Grizzlies — He ranks second among NBA sophomores in scoring with 18.1 points, a mark that leads the Grizzlies and represents a big hike over the 10.8 points he averaged as a rookie. Memphis has amped up the tempo to 103.8 points (sixth highest in the league) and the 6-9 Gay is their arrowhead, a versatile athlete who is improving his decision-making with the ball. “He’s picking up the whole idea of seeing what are they giving me,” coach Marc Iavaroni said. “If the defense says you should be going to the basket, then you should be going to the basket. If they give you a shot, then it’s your duty to take that shot.”
