They are elite level talents. 3 rookies on the same team with 60+ pts is so far from the norm.
Johnsson is not making that impact. Screenshot this post, and we can chat next year.
The reason why Johnsson wouldn't make an impact is if he is permanently stuck with a pair of 4th line plugs and limited to the 5 minutes a night that Kapanen, Soshnikov and Leivo have been for the most part over the past 2 years.
Despite your claims, I never stated Johnsson was likely to have a 60pt rookie season. I just suggested he is a good player who will likely make a good transition from a dominant offensive season in AHL as a 23 year old to the NHL. I don't think a rookie season like Brown's (or better) is out of question if he isn't relegated to a permanent place on 4th line with the likes of players of Martin and Moore's caliber. As we all have all amply seen, Neither of our 60pt rookies when they were dumped in the 4th line doghouse with the plugs put up the numbers they put up playing with actually capable players who can pass and score.
Or do you think that was just a coincidence Marner and Nylander didn't burn down the house when partnered with the likes of Martin and Moore (or the other plug center's we've had on the 4th line over the past 2 years)? Do you actually think that they would be having 60pt seasons on the 4th line? We've also seen that when players like Leivo and Kapanen aren't chained to plugs and get to play more than 5-8 minutes a game they put up decent numbers too.
Ideally, JVR, Bozak, Komarov and Moore are let go so our highly skilled younger players are given similar opportunities to what Brown, Hyman, Nylander and Marner have been given: the opportunity to use their skills where they are most likely to succeed. But sure, If you have older declining or plateaued players with limited skillsets blocking the likes of Johnsson, Aaltonen, Grunstrom etc. from making an impact, no, they won't, because they aren't being allowed to.
