Kopitar, Bergeron are not true superstar forward in the offense sense of the word but I take them over many pure offense star forwards like Marner for sure.
Sure let's play:
Crosby, Ovechkin, MacKinnon, Stamkos, Modano, Lecavalier, Staal, Kane were all 1st overall.
Malkin 2nd overall.
In all the players you listed for what? 3 decades+ Only Rantanen, Forsberg, Kopitar, Sakic were drafted outside the top 5 and were 1st round pick.
All the other names you listed were drafted outside the 1st round. So the chances are about 4 out of around 600 hundred to land a superstar forward outside the top 5 that won a cup. There is a very slim chances.
Let's say in 2023 the players who become superstar in the 1st round are Wood or a Stenberg and are both drafted outside top 10 are we going to re-visit this draft and say with clear certainty we missed the boat by not drafting them at 5th overall instead of higher rated prospect like Smith, Benson or Dvorsky?
The key is finding gems outside the 1st round, this is were you can accelerate a rebuild. You listed many players, we just need one or two to reach that level.
