It boils down to optimal playing time. A top-line player will get the best of everything, while a top-six player will receive decent even strength/second unit power-play ice-time. A bottom feeder will most likely receive checking line ice-time and less optimal scoring ice-time, which will hamper their scoring ability during the season. Their big break will only come if there are injuries or big sophomore slumps from their team’s top-six. There really isn’t a sense in projection 80 points for a player who isn’t even on a team’s top-line let alone top-six.
Note: Take the line combos with a grain of salt. They are just arbitrary and are used primarily to separate a team’s top-six from the bottom-six. I really don’t want to get into arguments about how Bobby Ryan is going to line up alongside Ryan Getzlaf and Corey Perry instead of Joffrey Lupul.
