I was wondering if we could decode the lettering neat to the year-size tag on NFL jerseys I have seen Q O S

Hi Eric. I believe S = Skilled, for skilled positions like RB, WR and DB.

O = Offensive line, probably

Q = Quarterback?

Certain positions are taylored differently, so that's probably what the code is for.
