My expectations for Necas are a little more subdued than maybe others. I think the kid has a ton of talent and his speed and ability to make plays at speed is enticing, but he is still pretty raw.
Svech last year, and Aho a few years ago showed a lot of progression in their overall game as the season went on. The two of them taking such a drastic step up their 2nd year, while not a given, were not a surprise either. Aho went scoreless forever his first season and started down the line-up before working his way up as the season progressed. Svech spent most of his time with Martinook and Wallmark as a rookie, but by the time playoffs rolled around, his overall game was drastically improved and his underlying numbers were great.
I did see improvement in Necas's overall game, but until/unless his 2 way game and strength improves more, I question whether Rod will him the same opportunities that guys like Svech and Aho got in season 2. That said, his 82G average was 20 goals / 46 points, which is nothing to sneeze at. He should be much more comfortable in the NHL and with Rod's coaching in year 2, so it won't take much improvement to add on another 5-10 points.
Foegele was on pace (82game) for 16G, 36P, but he shot a decent 10.1% SH% and was 6th among Carolina forwards for ES TOI. Without any PP time, which he likely won't get, getting much higher than that is probably going to be difficult, unless he moves up in the line-up, which could happen if Nino or Necas struggle.
