As Allen has insinuated, the Helton deal is dead. You can read about it here, courtesy of the Boston Globe.
There were a number of curious developments during the trade talks. It was rumored that this was a power struggle between Epstein and Lucchino (again), with Lucchino pushing for Helton. Lucchino is more fond of star-power than Epstein, but, personally, I don't believe it. "Seemingly drained and disappointed at not landing Helton, Epstein gave only a "no comment" in response to the ending of the talks last night."-Nick Carfardo
The Red Sox were also not pleased that the Rockies leaked Lowell's & Tavarez's names as pieces of the deal, and the Sox may need to smooth ruffled feathers. I bet the Rockies did it intentionally to put extra incentive on closing the deal.
The Globe's Nick Carfardo believes that talks may resurface during spring training.
