The league doesn't care about player safety. if they did, they would...
1. Have more strict standards for turf. Soldier field has been a mudpit multiple times this season, and when you combine a slippery field with "grass" made out of artificial turf on top of rubber on top of asphalt it makes for dangerous conditions.
2. Make all QBs, and maybe all players wear the helmet ARod's been wearing.
3. Serious fines for helmet to helmet hits that are anything but incidental.
When this whole CBA BS started I was 90% on the league's side. Now it's about 50-50.
