The Philadelphia Daily News (Paul Vigna) reports: Empty seats have been a chronic problem for the Sixers even before Allen Iverson left town. Now, even off last season’s playoff run and the offseason signing of Elton Brand, those low numbers are creeping back into the picture. Through four games, the Sixers are averaging 12,601 in attendance, ranking them 28th out of 30 NBA teams. That they started by losing five of their first seven hasn’t helped. Neither did that shadow the size of Yao Ming cast by the Phillies and their world championship.
