• Additionally introduction of new safety procedures such as non contact safety drills as well as padded mandatory practices further accounted for reduced concussions.

• Expand guardian cap mandates to additional game positions or situations
• Make dynamic kickoff permanent or apply similar constraints to other high risk players
• Target linemen for additional preventative measures given their high contact risk

• Position filtered visualizations to better identify who the concussion are most predominantly impacting
• Situation analysis of what type of contact is causing such concussions
• Emphasis on visual communication through diagrams rather than just pure data sheets
• Data recording made with time line graphs with rule changes that could demonstrate cause and effect / the successfulness of rule changes
• Visual analysis through recorded footage that could then be translated to a data sheet describing the specific events that caused a concussion
