Bergeron had 57 points in the year they won the Cup
Toews had one 70+ point season (non-cup year)
again, not "superstar" numbers..Superstars finished in the top of the scoring race and win MVPs
Actually, Superstars lead their teams to victory and are selected to compete in best on best tournaments (especially when Team Canada).
Why are you quoting what those players have done in the regular season when you seem to have an issue with them not being legit superstars but still won a cup(s)?
Toews - 3 time SC champion (2009, 2012, 2014)
2009: 7 goals/22 assists/29 points in 22 games played
2014: 10 goals/11 assists/21 points in 23 games played
Bergeron - SC champion (2010)
6 goals/14 assists/20 points in 23 games played
Seems like they played at near superstar level in the playoffs during their cup runs, not to mention that both of these players are viewed as complete players and not as offensive only players (ex: Kessel).
