Over the weekend the Boston Globe's Greg Bedard noted that the last three Super Bowls champions had only one unrestricted free agent starter in his first year with the team -- combined. (I'd embed the link but the column is behind a paywall so if you want to see it, go get it. I recommend you do). Anyway, while that is a very interesting and consequential fact that suggests Super Bowl teams typically grow a majority of their own talent and need their imported talent to adjust for more than a year before succeeding at the highest level, I can see the fact also has the potential to be misunderstood.
