The Nets Shop by adidas is fully stocked and awaiting its first customers Monday morning, starting at 10 a.m. with a ribbon-cutting and autograph session with Brook Lopez and MarShon Brooks, both of whom are adidas athletes. The store is one of several retail outlets with entry from both the street and the arena concourse. The stores, which will ultimately include Rocawear, MetroPCS, the Elbow Room and other brand name stores, are known officially as "The Shops at Barclays Center."
