It's not a misnomer.
Go through every draft since the league expanded to 12 teams, its rare to see every first round player appear in even one game. How rare? Well, if Forbort plays and makes it so everyone from the first round of the 2010 has appeared in a NHL game it will be just the seventh draft ever to see this happen. The others were 1973, 1977, 1978, 1979, 1983, and 2003.
If you remove the drafts where the highest drafted player to not play in a NHL game was drafted higher than 31st overall (thus making it equal to a 1st rounder today) That number drops to just four drafts; 1977, 1983, 2003 and 2010.
When I said it is rare for every player in the first round of the draft to make the NHL it is and we are talking over an entire career. The guys from 2010 are all 21-23 years old, they are just starting their careers. The fact all 30 have reached the NHL at this point in their careers should be applauded and acknowledged as amazing.
