The Dolphins beat reporter for the Palm Beach Post is saying that the agreement with J Long is almost finalized.
In a live radio interview he said that anything could still happen until it is signed, but that the basic terms were all hammered out and agreed to. He speculated that ithe deal, even if finalized, might not be announced today since it is late in the day to put together the press conference for maximum media coverage. Tomorrow is more likely, but there is no hurry.
