Al, all the defender did was cradle the BC’s entire head between his forearm and his upper arm. At no time did the defender grasp any helmet opening, or any part of the facemask or chin strap. The loosely fit helmet simply slipped right off the BC’s head. This was NOT a facemask foul, as defined. The helmet coming off the BC was a helmet-off violation, and the only thing that should have happened was sending the BC off for a down, unless his team took a team time-out.
