The Nets set Alston free yesterday, and it looks as though he’s about to rejoin the Heat: “The Rafer Alston buyout is done and the Nets are finalizing their deal with the Heat to acquire point guard Chris Quinn. Alston, basically, agreed to knock $1 million off the $3.107 million he had remaining on his $5.25 million salary. Once he clears waivers, then he’ll join Miami. The Heat, meanwhile, are sending the fourth-year PG Quinn – picking up the remainder of his $1.05 million salary in this his final contract year, about $640,000 – and a 2012 second rounder to the Nets. The Nets are sending a $1.2 million trade exception plus a protected second rounder in this year’s draft – a pick they’ll never give up unless there is divine intervention in New Jersey. The pick is protected to 50. Anything lower, it stays put.”
