Alan Anderson was the 15th and final player Nets general manager Billy King signed this summer to round out the team’s roster. But two games into the regular season, it already is clear Anderson wasn’t signed to watch from the bench. As he had in the season opener, Anderson played more minutes than any player off the bench Friday night, and he contributed eight points, four rebounds and a blocked shot in 25:29 during the Nets’ 101-100 victory over the two-time defending champion Heat at Barclays Center. “We needed a strong bench,” Anderson said of the sales pitch the Nets gave him this summer. “That’s what [general manager] Billy King and [coach Jason] Kidd told me, that they needed a strong bench. “That’s what wrong with a lot of championship teams … not everybody accepts their role. Not everybody is a starter, not everybody is a star player. I know I’m not a starter, but I don’t mind coming off the bench. That’s what I knew, that’s what they told me and I’m just here ready for whenever my number is called. “It might not be every night, but when it is I’ll be ready.” So far, so good for Anderson, who seems to be firmly inside the Nets’ rotation even as Andrei Kirilenko continues to see his minutes increase after missing the final two weeks of training camp and the season opener with back spasms. A big reason for that is Anderson’s versatility. When Shaun Livingston got into early foul trouble Wednesday in Cleveland and Deron Williams was saddled with a minutes limit, Anderson was the pick to fill in at point guard. That’s in addition to his ability to play shooting guard and small forward, a pair of spots where Anderson spent plenty of time throughout Friday’s win over the Heat.
