I usually like your trade suggestions. If you think we need a d-man (and I'd agree) who would you target?
the market is going to be limited since so many teams are still in the race.
i think zeke mentioned it a few days ago - i wouldn't be against going after brewer. i've long thought him to be overrated, but at $4mn he carries decent value, and is only signed until he's 35 so that contract is moveable. he brings a bit of everything, which i like, and is actually pretty comparable defensively to bouwmeester (not as good becaise he doens't have his foot speed, but they play a pretty similar game).
hejda, if colorado would move him.
phoenix also has some interesting pieces -- michalek or morris would help - and i especially like them since they are both right shots (taking carlyle's right-left split into account).
if dallas starts moving pieces daley or robidas would fit the bill.
as for what i would give up... i wouldn't hesitate in any trade to give up some package of 2nd rounders (2013 and 2014), d'amigo, ashton, ryan, mckegg, percy, leivo, brown. if you're getting a guy with prime years left in him and term then you can discuss biggs, colborne or finn.
