These rankings represent the
informed opinion of our staff
about which teams have done the most to improve this spring, and not
something like which teams are most apt to win the Super Bowl (see Browns, Cleveland).
Now of course these judgments may be
informed by medical observations — for instance, when the brain develops to a certain level, or when
something will end up naturally growing into a born human without any further intervention — or by pragmatic considerations, gut feel,
opinion polls, tradition, views
about how precise and clear legal lines should be, or whatever else.
