Practicing in Toyota Center on Thursday morning wasn’t a new experience for Oklahoma City guard Jeremy Lamb. Although he has played only five minutes of one regular-season game on the floor of the venue, it remains a special place to Lamb. It is where he got his NBA start. It has been 11/2 years since the Rockets picked Lamb 12th overall in the 2012 NBA draft. In the last couple of months, the young guard from the University of Connecticut has turned heads playing for the Thunder. Lamb spent the 2012 training camp and preseason with the Rockets, averaging 11.7 points in preseason games. On Oct. 27, just before the regular season started, Lamb was traded to Oklahoma City along with Kevin Martin, two first-round draft picks, and a second-round draft pick for James Harden, Cole Aldrich, Lazar Hayward and Daequan Cook. “It was surprising to get traded,” Lamb said. “You hear about that, but when you go through it, it is like, ‘Wow.’ But everything has turned out good. I am feeling OK about my development.” Lamb, who is averaging 9.9 points, 2.8 rebounds and 1.5 assists in 21.9 minutes off the bench for the Thunder, continues to get better. In December, Lamb averaged 10.6 points off the bench. More impressively, he shot 50 percent from the field. This month, his scoring average is down slightly (9.9 points), but his rebounding average went from 2.8 to 4.1. His assist average went from 1.6 in December to 2.1 in January.
