The problem is that its tough to expect much trade value of the 4A players. Norris for Olson is the exception, not the rule.
I don't think its a playoff team. I would expect Rodriguez and Lorenzen to be traded. I don't think there are enough remaining SPs to keep the team afloat given the offense. Heck, I don't know if there would be enough remaining healthy SPs to begin with.
I kind of wonder if Carpenter and his inexpensive offense would yield something worthwhile in return, but his defense is compromising. I'd be comfortable with him as DH next season, but I don't really want a long term DH. I'd prefer the offensive players be able to play competent defense, too. Ideally the DH spot could be used for a partial day off or guys dealing with injuries (kind of like Greene now).
