Last year I think we had one or two players, maybe Rapp?, who wore the helmet pillows (I guess they have some sort of official name but that's what they look like to me).
This year I don't think any Bills are using it and I'm surprised that it hasn't caught on around the league, considering what appears to be an obvious safety benefit. OK, they look ridiculous, but probably face guards did too when they were new.
(Kinda reminds me of hockey back in the '60s when only one or two players wore helmets, and the Amerks had a goalie, Bobby Perrault, who didn't wear a mask or a helmet at all. He's dead now.)
Anyway I'd love to have the wisdom of my fellow posters on this all-important topic.
