NFL Priorities

Which of these three NFL issues deserves the deepest continuous attention by the league, by fans, by the media, and by the public?
1. Frequent on-field concussions that demonstrably lead to players having permanent brain damage, diminished quality of life, and premature death.
2. Frequent off-field antisocial and possibly criminal behavior by celebrated players.
3. A possibly deflated football.
Note: It is possible that more scientists have been covered talking about the football that New England Patriots quarterback Tom Brady may have had deflated than about the concussions in the NFL.
