Sleeper League: Defensive Scoring in League with no DST or IDP?

Like the title says, do you setup defensive scoring in a league with no DST or IDP players? Logic is to give that random skill player who plays special teams or the QB who gets a tackle after an INT the point they “deserve”. Thoughts? Does it even work, or do they need to be slotted in a defensive position or IDP position to receive the score?
