Unrestricted free agent Ray Allen is torn on whether to leave the Celtics, sources tell ESPN.com. Allen left his meeting with the Heat on Thursday night without giving them an answer. The Celtics have offered a two-year, $12 million deal that includes a no-trade clause. The most the Heat can offer is their mid-level exception, up to three years and $9.5 million. The Timberwolves are also reportedly in the mix, but are a longshot at best. There's no timetable on a decision right now.
