Gentlemen... the NFL are in ass-saving mode. The media are ripe for the concussion issue, they've got THAT ball and are running with it. The media gets their story and the NFL is on the hook for billions in lawsuits from past, current and future players, their families and ancestors. Football concussion long-term effects is an ambulance chasers wet dream, likewise for class action lawyers. One way for the league to mitigate damages is for them to "get tough" on plays that might be considered blows to the head.
It's all about mitigating damages, and Earl is in the damage path.
Bullshit call, bullshit fine, bullshit rule.
