NFL COVID-19 Helmet Concept

Extra weight /stress on the neck, is a worry. Neck/head injuries & concussions are all exacerbated by helmet weight.
I can't see a huge risk of breathing/vision difficulties. A motocross rider is under more stressful circumstance. Dust, sweat, exhaust & speed all are greater than in football, w/NO breaks. The design "appears" to be more conducive to airflow.
I still don't see much hope in the season anyway.
