Correlation=/=causation. The big difference between last year and the prior post-lockout years was Lundqvist doing 99% of the work instead of 98%. The offense actually declined from the prior season, remember?
Correlation doesn't equal causation . . . except when it does, and this is certainly one of those times. If you want to make a list of reasons for the Rangers success in 11-12 as compared to 10-11, Richards is clearly #1 in my book. McDonagh would probably be #2. Lundqvist played no better or worse than he has played throughout his NHL career, which is to say that he's been elite from the get go.
And the offense declined at a slower rate than the rest of the league. The Rangers went from being 16th in goals per game in 2010-11 to 11th in 2011-12.
