Are any of these guys upgrades over my current roster?
As far as strategy goes, I think I could use some more goal scoring. I think I have a decent amount of grit in Backes, Horton, and Clowe, but I could be wrong. Also, dual-eligibility would be a plus, but I do have a fair amount of that already.

FW: Doan(LW/RW), Erat(RW), Hudler(LW), Tanguay(LW), Hornqvist(RW), Downie(LW/RW), Cammalleri(C/LW), Little(C/RW), Dubinsky(C/LW), Schenn(C/LW), Kulemin(LW/RW), Stewart(RW), Ott(C/LW), JVR(LW), McDonald(C/LW), Dupuis(LW/RW), Kennedy(LW/RW), Clutterbuck(RW)

D: Subban(NA), Wisniewski, Carlson, Pitkanen, Smith, Whitney, Faulk, Hamonic, Ellis, Liles

Subban seems like a no-brainer to me, over Markov, but I drafted Benn too so I'd have to roster spots tied up with players without contracts.
