Couldn't disagree more! The years the Sedins won their scoring titles they led the league in offensive zone start %, they were above 70%... Source =

If you want further info about the impact zone starts can have see below, mckeens has an outstanding article. It's literally a statistic, you generate 0.8 more shots per shift starting in the o zone than the defensive zone, so obviously if you get a higher % of starts in the o zone you're going to get more points because shots produce goals and goals produce points.

Do you have stats for the 2009- 2010 season when Henrik won the Art Ross and Daniel had similar ppg numbers? I'd be curious to see if the bump in production was due solely to zone starts.
EDIT- found it myself
2007-2008 - 54.8 === 76 points
2008-2009- 49.9 === 82 points
2009-2010-
57.7 ===
112 points
2010-2011- 71.4 === 94 points
2011-2012- 78.6 === 81 points
By far Henriks best season occurred with 57.7 percent offensive zone starts, hardly that lopsided.
If you're going to be lazy and use zone starts as the reason for their production, explain why the most similar season to that one he ended up with 76 points.
After explaining that, explain to me why
57.7 % O zone starts lead to 112 points
whereas
78.6 % O zone starts lead to 81 points
It's an extremely lazy argument and you'd have to throw away pieces of data and ignore other pieces in order to make it fit your narrative.
I'm not sure why it's so hard for people to credit them for their breakout instead of running around trying to find reasons to discredit it. Here's my reasoning
1) They were dominant
2) They had a better supporting cast around them
Now they are lesser players and play with very little talent around them.
