Easy to imagine. In 2011, we had a 40 teams ATD, plus several minor league drafts, MLD, and beyond. Then you can add 14 years of hockey history to this, and you get a good picture of what it would look like.
Edit:
ATD2011 = 1000 players
MLD2011 = 350 players
AAA2011 = 250 players
AA2011 = 72 players
= 1672 players.
Add in the previously unknown old-timers, and the moderns/actives, and it more or less cancels out to 2000. And you get those type of players:
The 2011 Double-A Draft (sign-up, roster, picks, everything)
The Martin Rucinskys, Sergei Samsonovs, Jason Blakes of the world. Not too shabby actually. Many household names still.
