Each year, the NFL evaluates what players were gained and lost in free agency. When a team had a net-negative gain, the NFL will award them compensatory draft picks. If you had a net-positive gain, you get the results in wins and losses.
Based on last year's offseason, Miami received NO compensatory picks, in spite of the roster churn (now I'll grant you, its hard to measure a 1-15 team as being any good). The Jets and Bills similarly got no draft picks. But the Patriots got 3 - a 3rd, a 5th, and a 6th.
That seems a little biased to me. I guess this is Goodell's way of saying "I'm still really sorry, Billy, about ever questioning you. Here - have some more draft picks."
