I've been pleasantly surprised by the details of Snuggerud's game. I figured his shot would be at an NHL level, but I was expecting most of the rest of his game to be further behind than it currently is. He's more NHL ready than I thought he would be. He looked nervous in his first game, but by the 2nd game onward he's looked solid. He still makes rookie mistakes from time to time, which is going to happen, but I have been impressed by a lot of aspects of his game that I didn't expect to be "up to speed" for the NHL yet, or to be positive abilities at this point in his development. His passing has been great. He's able to make quick passes under pressure, and it's usually on the tape or it's a quick clear. He's made a few plays that really showed glimpses of his vision as well. That quick turnaround pass through the neutral zone right on the tape of a streaking Thomas in game 2(?) comes to mind. He seems to think the game pretty quickly, at least quicker than I was expecting. He also doesn't appear to be out of place in terms of physical play either. He's throwing hits, and he's taking/avoiding hits pretty well without turning the puck over, which goes back to his quick passing/thinking/vision. He doesn't appear to be shying away from it, and he's weathered it pretty well considering how physical this series has been so far.
In short, he's a more complete player than I expected. He reminds me of when Neighbours had his 9 game stint as a rookie. Not in terms of play style, but in terms of "this guy doesn't look that out of place for a 19-20 year old." Snuggerud I think has already shown that he has more skill than Neighbours did at that stage, Neighbours was probably more physically ready.
I wouldn't be shocked if at some point Snuggerud can reach that 30-40-70 range, maybe even higher. I don't think it will be next season, though. I think your prediction is much closer to what he'll actually do next season, or at least a reasonable, high-end expectation. I do think he's going to put up more assists than I originally thought he would, based on what I've seen in this small sample size.
