The NFL honestly has to start trialling football without helmets; perhaps the old fashioned leatherheads or the updated rugby caps. IMHO that`s the only way players will learn a new culture, and learn to bloody tackle properly.
As for Burfict, his career may be over, and it`s all his own fault. What he did was stupid and dangerous. It`s (another) pity for our team as he was playing well and perhaps our best defensive player, called the plays etc. He`s obviously got issues.
What i don`t get is the Raiders starting the season with 4 LBs on the roster (plus one who was the ST captain), and have now lost one to suspension and another to season-ending injury. That`s on the management.
