My concussion policy.
Here's what I would implement immediately:
1. Find the best anti-concussion helmet technology an make it MANDATORY.
2. Conduct study to determine whether there is a correlation between artificial playing surfaces and concussions. If there is, require the use of whatever artificial surface is determined to be the lowest impact type in existing dome stadiums, and require all new stadiums to be open (or use retractable domes) to allow for natural grass surfaces.
3. Mandatory minimum of 1 week off for any player sustaining a concussion. Severe penalties for teams who fail to report a concussion in order to avoid this policy.
4. Mandate that any player suffering more than one concussion in a single season MUST be placed on injured reserve. Again, severe penalty for failure to report incidents.
