"Through it all, my heart never wavered," he wrote.
The Knicks can pay the All-Star forward nearly $130 million over five years, though Anthony has said he would be open to taking less than the maximum salary if it would help build a winning team.
Anthony decided four summers ago he wanted a trade from Denver to New York, and the Nuggets were finally able to accommodate him in February 2011. Anthony, who was born in Brooklyn, wrote in his posting that at that time he had dreamed of coming back to New York.

Source: Pierce agrees to deal with Wizards
Paul Pierce turns 37 in October and isn't quite the offensive force he was when he was leading the Boston Celtics to the championship seven years ago.
The old man showed last year in Brooklyn that he still knows how to knock down a clutch shot and grind out a playoff series victory, which made the up-and-coming Washington Wizards eager to add the man known as "The Truth."
Pierce and the Wizards agreed to terms on a two-year deal on Saturday night, a person with knowledge of the agreement told The Associated Press. The deal is for the mid-level exception, which is about $5.3 million for next season, and includes a player option in the second year of the contract. The person requested anonymity because the Wizards have not officially announced the signing.
