Aginor, that is my point though that we have many different eras represented, and because of that, we already have certain guys in the league who are must haves when you draft in an open league. You need to have them because their offensive stats are so skewed because of the eras they played in. At least it was NHL though.
Malone, Dye, Denneny they did play in an era when a few guys racked up ridiculous amounts of goals and hardly any assists. Then you have the 80s and early 90s players that benefited from rapid expansion of the league leading to a time when scoring was off the charts. There are some D men from the 70s and 90s that have huge numbers during times when scoring was down league-wide.
In the end though, its all NHL and even though the eras differ, they are all NHL players.
If this is going to happen, these guys can't be available to open leagues. Comparing eras is one thing but comparing leagues is a whole other ball game. Although many good players the NHL for the WHA, most did not. The good WHA players were playing against inferior opponents, thus inflating their stats. All other eras have the best competing against the best. (although you are correct about the early years but if you choose a guy like Malone you are automatically punished by the high PIM and low assists).
I am not against the WHA stats being available in some capacity, I just don't want them to be considered equal to NHL stats.
When we had the olympic leagues recently, it would have been really cool to have stats from the 70s KHL and Swedish league.
