I agree. There's no way the Rockies would do this unless young talent is included, and given the sox recent track record (Anibal Sanchez, Hanley Ramirez), I'd just asume keep Youkilis at 1B and Lowell at 3B. Lowell and Youk are good defensively, and offensively they'll produce about the same as Helton anyway:
Helton .302-15-81 in 649 ab - .266 on the road
Youkilis .279-13-72 in 569 ab
Lowell .284-20-80 in 573 ab
Helton's power is going in the same direction as Don Mattingly's after his back issues. A nice player, but not even an average 1B offensively at this stage of his career. And remember, this is what Helton produced in COLORADO...stick a fork in him...
What exactly does Boston gain? They get to rid themselves of the burden of developing young talent
