BROOKLYN - A basketball rivalry could be brewing in Brooklyn as the Knicks put up an ad right near the soon-to-be Brooklyn Nets arena.

The team put up a large sign on the side of a building featuring A?mare Stoudemire just blocks from where the Nets stadium is being built. Stoudemire stands in front of the Manhattan Bridge with the tagline 'Brooklyn Represent.'

The Nets arena is expected to be complete by 2012.
