NFL will look at the fumble-out-of-end-zone rule

Yeah he did....totally didn't see that.

But yeah, still don't agree with the changing of posession on a fumble out the side of the endzone. There's already a rule mechanism in place to deal with forward fumbles out of bounds...specifically on 3rd downs where forward fumbles out of bounds anywhere on the field are spotted at the spot where posession was lost. Expand that ruling to include fumbles out of the side of the endzone and viola - the source of frustration for fans all over is gone.
Of course the end zone is surrounded by an "out of bounds." Or else a receiver could run as deep or as wide as he desires in order to catch a pass. The rules for a reception in the end zone include the requirement that the receiver must have and maintain possession of the ball BEFORE GOING OUT OF BOUNDS.
