There seems to be a harder and longer transition period to the NHL for rookies these days, resulting in a lot of players busting early. For instance, Yzerman, 22 years ago, had what would be considered a very good draft year (he was picked 4th overall) posting 91 pts in 56 games with Peterborough. The next year he made the jump to the NHL and led the Wings in scoring (he was only 18). Now I can't imagine any 18 year old (and that includes Crosby, Ovy) jumping in straight away and post excellent numbers. There are many cases of that in the '80s as well (Jimmy Carson, Lafontaine, etc...). Has the NHL improved drastically over the years?
