The NBA has informed teams that it is projecting a rise in the salary cap of nearly $5 million for next season, which could aid clubs such as Chicago and Houston in their attempts to steal free agent-to-be Carmelo Anthony from the New York Knicks, according to sources familiar with the forecasts.

Sources told ESPN.com that all 30 teams were informed this week via league memorandum that an increase in the cap from this season's $58.6 million to $63.2 million in 2014-15 -- thanks to increased revenues -- is now expected. A corresponding rise in the luxury-tax threshold from $71.7 million to $77 million is also projected, sources said.
