You just make it too easy.
The Yankees 4 Championship teams since 1996 averaged 192 HRs. The 9 non champ teams averaged 209. So, you see a philosophical difference that is costing them championships by having an additional home run every 10 games???
The Red Sox HIT WELL and PTICHED POORLY because they were in the most hitter friendly park, not because they favored hitting. They had more power than speed because their ballpark deemphasized the value of speed. Duh.
Kobe Bryant, Michael Jordan, DeWayne Wade, etc say hi and wonder why you think they couldn't beat those low post teams they beat.
You have now decided to compare NFL teams with good defenses AND good offenses to teams with only good offenses and have come to the miraculous conclusion that the former do better than the latter. Hooray for you!!!

Those are pretty damn good power numbers throughout. Yet another useless point by mav that is easily refuted, it looks like.
Actually, the real argument that's been raging across baseball over the last decade-plus is the traditional sabermetric approach that was popularized in Oakland in the late 90s was to get high OBP guys who could hit for some power, while deemphasizing a number of other skills (namely, speed).
I say traditional because the philosophy has changed: what it's really about is finding elements that correlate to winning yet are undervalued in the marketplace. So, once Billy Beane disciples ended up in Boston, Toronto, etc., the market corrected to appropriately value OBP, and nowadays you see Oakland teams that emphasize strong defense, which is now extremely undervalued (largely because not all teams quantify it well).
Anyways, if you can analogize the Pats' offense of the past few years to any offensive philosophy in baseball, it's the traditional sabermetric approach. In either case, you're preferring the statistically superior approach, at the expense of situationally "manufacturing" progress in sub-optimal ways.
So let's look back at the Yankee dynasty's OBP for those years:
1996: 3
1997: 1
1998: 1
1999: 2
In short, the sabermetric approach was proven right largely BECAUSE of the Yankee dynasty. They were all about getting guys on base and letting statistical probability take care of the rest. That means less first-to-third on singles, less steals attempted, etc.
