The Bleacher Report is apparently a fan of signing as many 2005 Chicago White Sox to the 2010 Houston Astros as possible, and this article says the Astros should sign Jermaine Dye:
What is somewhat unclear is whether he still has anything in the tank. Dye, 36, suffered through a miserable second half last season that has scared off all potential suitors this winter. After leaping out to first half numbers that included 20 home runs and a .302 average, Dye fell into a slump that lasted the remainder of his season. After the All-Star break, he hit just .179, and slugged less than .300.
With such a well-established performance record, however, it would behoove several teams to at least consider giving the two-time All-Star a chance to prove himself. Dye has said this off-season that he would be open to a move to first base, so the Astros could use him as a fourth outfielder (current stop-gap Jason Michaels is an unsatisfactory choice), a top-tier pinch-hitter and a good back-up option to Berkman, allowing the switch-hitting slugger to stay fresh as the season wears on.
There are two big "Ifs" here: (1) If Dye would take a bench role, and (2) if Dye would take a LOT less money. I don't see it happening, I don't think the Astros are interested, and I would be very surprised if Dye was, too.
