I don't see them trading HanRam at all.
1) He's been his healthiest since the move to 1B.
2) If he becomes our FT DH after this season, I don't see him getting hurt all that much or at all.
3) His attitude has been great from the beginning and let's not forget that HE's the one that wanted to come to Boston.
4) A rebuilding team looking to trade a TOTR SP (like Sale) won't be looking for a high priced veteran in a deal. They'll want guys like JBJ. Not sure what we can get in return trading HanRam, although the Yanks did rake on trading 2 months of Beltan... but situations are different mid-season compared to the off-season.
You're right that he's had a fluctuating career at the plate, but it might not matter if he hits .881 or 1.040. To me, as our DH middle of the order bat, just give me the RBI. This season, Hanley has already tied his career high in rbi (106, 2009, age 25, .954) w/ an .881 OPS. The Sox, as presently constructed, get on base and I don't see that changing any time soon. I think he's a perfect fit for our team going forward.
