I've had this theory for a long time that really doesn't hold much water. It goes like this:
Find a team without good 40 man roster depth, and needs at so many positions, they may actually want guys like DHam, Grissom, Wink, Murphy, Kelly, Guerrero, Sogard and the like.
Offer them 2-4 of these guys for one player that is maybe just marginally better than any one of the guys given up. We would improve at one slot, maybe even be a guy who can start for us- the better team or be a player that fits a greater need for us than the guys we traded away. We also have like players in the system that can replace the depth we lost and barely be step downs.
Of course, the reality is no team wants 3 scrubs for a slightly better than scrub player.
Since our 40 man roster is not really in crunch mode, this winter, this theory is not really something I'm looking at, but I do think we can look to trade 2-3 good/decent players for a better one (and maybe add one borderline player, if the other teams needs one.)
Duran is not a scrub, but I think offering Fitts and Crawford with him, might entice someone to give us the #2 SP'er we need (maybe a third team is involved.)
