Anthony denied that in an interview with Yahoo! Sports' Adrian Wojnarowski, explaining that one of his biggest reasons for wanting out was the direction the Nuggets were headed in.
"People didn't really know the business side of the situation we were in," Anthony said. "Everybody's contract was up. They had plans of going younger. People from the outside looking in didn't really get it."
Following the 2010-11 season, Kenyon Martin, J.R. Smith, Marcus Camby and possibly Chauncey Billups were going to be free agents that were likely to go elsewhere. With Denver planning to go younger, Anthony decided that he did not want to be a part of a rebuilding process. So he pushed for a trade to New York to avoid a rebuild and to also take advantage of the major marketing opportunities in the city.
