If Tkachuk is available at 6, I only take him if all the 1A Dman prospects are gone. Of course if that's true, then either Zadina or Svech are available. So no, I don't see any scenario where he gets picked by Holland.
1st bold: Agree.
2nd bold: Disagree here. They will go Dobson if he's still there, or Ty Smith if he isn't. They'll be looking to replace Duncan Keith on the blueline.
