Twarynski really regressed from TC, of course, some of the line combos for LHV, especially with Rubtsov out, aren't favorable to young forwards. But he looked better than NAK in preseason. I expect Twarynski to pick it up the second half, NAK started slow last year, and Bunnaman is just now making a little noise.
I never saw NAK as the replacement for Voracek, a bottom six RW but not a scoring threat.
My point with JVR was that early in the season, losing a major piece hurts more than later in the year when young forwards on LHV have enough experience under their belts to fill in, allowing other players to be promoted up a line. You hope to get through the first half of the season relatively unscathed for that reason - Stolarz is a good example, we got lucky because he certainly could have used a half dozen more AHL starts before getting recalled.
Sanheim should become a bigger and better Ghost or he's a disappointment, the skills are there, and he certainly has size, reach and straight line speed over Ghost - if the recent shot he's shown is for real, he closed another gap. He'll never be as agile or quick as Ghost, though Ghost is not nearly as quick or agile as rookie Ghost - he looks like he never came back 100% off surgery.
