Everyone's season winds down in March and for some it's a late-season surge (Nash, Kytnar) to the playoffs, for others, like the parent club, it's just playing out the season so that they can get home to their family and friends. Nash was on fire to end the season as Cornell charged to the NCAA playoffs. Riley Nash's NHL PPG at the end of December was .410. In January that dropped to .319, but in February Nash rallied and pushed it back to .461. Now, at the end of the season, Nash's charge peaked with the final game - .478 and 3rd in NHLE for all Oilers not in the NHL.
NHLE was developed by the irrepressible Gabriel Desjardins of the Behindthenet.ca and the outstanding Behind The Net Hockey.
Gabe's methodologies are described on his translations page:
One way to evaluate the difficulty of one league relative to another is examine the relative performance of players who have played in both leagues. Players rarely play significant time in two leagues in the same year, but they often play in one league in one year and in another the next. As long as a player’s skill level is approximately constant over this two year period, the ratio of his performance in each league can be used to estimate the relative difficulty of the two leagues.
