The link to the study is interesting, but...

To extrapolate success or failure based on it is silly.

To say that the Pats have schemed to be heavier is also silly. We are talking a different of 1 (on the bmi scale). That is not much, if you took a 6'0" person, to change his BMI by 1, he needs to lose or gain 6lbs.

So, does having an average weight of about 6lbs, really make a difference? I would doubt it. Even if you took an offensive and defensive individual matchup and one had 6lbs on the other, would it really play into the matchup?
