What is a SN.

[KLHJ2]

After cross referencing several rosters SN stands for snapper. Most of us are familiar with LS for longsnapper, but whatever. I cannot believe that they actually designate a roster spot for a special teams job outside of Punter and Kicker. A gunner still has a WR, SE, DB, CB, ROV, or S designation on the roster. A personal protector is still a LB or FB when it comes down to it. Why not just list a LS as the position he would play on the field instead of his special teams duty? Rant over.
