2. No one is arguing that on paper Pittsburgh looks like the best offense in the NHL. The argument is that they will not have one player win the Art Ross AND TWO DIFFERENT PLAYERS finish in the top 5 in goals. Yes Malkin and Neal had great years but if Crosby plays all year he takes chances away from the previous two as mentioned.
Saying the Pens offense is the best because they were last year isn't a very convincing argument. The Flyers offense was number 2 last year and I doubt they will replicate that. Hartnell scored 37 goals last year and I doubt he repeats that. You also lost a center playing on your 3rd line that routinely puts up 20-25 goals and 45-50 points. Your powerplay and top line (maybe even top 2 lines) will be awesome but it drops off quickly from there in my opinion.
Last years offense has little impact on this years offense and this is a forum so yes everything is debatable especially when trying to predict the future.
