From James Murphy (who's been all over this of late): While the parameters of the (potential) trade are unclear at this point, a very reliable source told NESN.com on Friday that the Bruins are closing in on a trade with the Florida Panthers that would see them acquire winger Nathan Horton... According to this source, who stressed the Panthers were talking to numerous teams about Horton and could still accept another offer, "the parameters" of the possible trade were still being worked out as of late Friday afternoon, but "Horton believed he could be very close to being a Bruin." So...Boston or bust?
