NEW YORK — Thursday night when the Miami Heat face the Nets for the first time since Brooklyn’s league-shaking summer trade, LeBron James and Dwyane Wade think some ex-Celtics on the Nets might owe the ex-Celtic on the Heat an apology.
A year ago there was a stream of vitriol from Boston aimed at Ray Allen after he chose to sign with the Heat in the offseason. Kevin Garnett said he lost Allen’s number, Paul Pierce said he hadn’t forgiven him and Doc Rivers implied Allen had an ego problem.
Now all three of them are also out of Boston, agreeing to go to teams seemingly on the brink of contention instead of sticking around for Boston’s rebuilding project. Garnett waived his no-trade clause so he could go to Brooklyn in a package with Pierce after he agreed to the deal. Rivers engineered his own trade that allowed him to become the coach of the Los Angeles Clippers.
