This. I used to argue on here constantly that our #1 priority was finding another legit top line forward to replace Seguin/Horton/Iginla.
I still think this is important (a #2 priority...) now that Hamilton is gone and we have no obvious Chara heir apparent, our #1 priority now has to be acquiring a young #1D. Someone of Shattenkirk's stature; whether via trade or drafting. My ideal candidate would be Shattenkirk (who I don't think the Blues have the cap space to re-sign in two years) or trading for a higher pic or tanking radically this year in order to draft Jakob Chychrun.

If we draft Chychrun next year, I think he's going to be good enough to step into a top pairing role beside Chara, the way Ekblad was able to do last year. Check it:

If we need to give up an Eriksson or a Krejci to do acquire a Shatty or a pic to draft Chychrun, then pull the trigger (and for the record, I also think Eriksson is a walk on top 6 winger).
Otherwise, no way in hell I'd give up either for Buff, who I'd never sign to a long term contract (I envision him showing up at training camp at 350lbs in year 3 of a long term contract).
