That is supposed to be a snack tray. The top of the helmet is an ice bucket and the face guard has two small trays for - I don't know... - peanuts and salty snacks?
I couldn't tell ... I thought it looked like some sort of strange hospital bed pan ... or a toddlers toilet trainer
And if they were those things, I thought it was funny that it was all sponsored by the NFL ... and judging by the way the US is going, I wouldn't be surprised if this contraption was meant for toilet use.
