In the future, we might look back at the 2016-17 class of rookies as one of the best the NHL has ever seen.
Only a year removed from Connor McDavid and Jack Eichel owning the spotlight, the 2016 No. 1 and No. 2 picks put on a show in their debuts. And they were hardly the only ones. Fans around the league saw the emergence of exciting rookie scorers, top-pairing defensemen and even a franchise goalie.
But every season, some of the top rookies from the previous campaign hit a wall. Whether it's because opponents adapt or because coaches put more on the shoulders of their young players or simply a regression to the mean, the sophomore slump can be "a thing" in the NHL.
In 2015-16, for example, Arizona winger Anthony Duclair looked like a rising star, putting up 44 points in his rookie campaign. He followed that strong start with just five goals and 10 assists in 58 games in 2016-17 and saw his shooting percentage drop from 19.0 percent to 6.6.
On the other hand, we also saw McDavid rocket from a strong start as a rookie to winning the Hart Trophy as league MVP.
How will the historically good 2016-17 class fair in their sophomore seasons? We're breaking out the Sophomore Slump Threat Index:
Green: Not a candidate for a sophomore slump
Yellow: Sophomore slump a possibility
Red: Good chance of sophomore slump
