An NBA executive said that there has been "zero" trade talk involving Celtics guard Ray Allen.

There were rumors to the contrary earlier this week, and the executive went on to call such rumors "preposterous."

Allen will be a free agent in the summer of 2010, which could make him an attract target on the trade market.

"I'm not really hearing that. But I would expect that kind of rumor," another executive said. "They didn't win without KG [Kevin Garnett], he was hot and cold in the [playoffs], and he's a last-year guy. Upgrade if you can. It would make some type of sense."
