What's the difference between All DB and All CB/S

Probably different pink haired EA interns making the cards who dont understand football

But they cover the same positions

Not sure why some are labeled CB/S vs. All DB, but as mentioned below Legendary Ballhawk (CB/S) boosts all DBs (both safety spots, and corners). Strats like In the Zone (All DBs) boost the same position groups, but it’s unclear why they’re labeled differently.

CB/S doesn't include FS, at least that's what I'd assume.

Shouldn’t be any difference

I asked this too and didn’t get a clear answer.. i can confirm that the legendary Ball Hawk boosts all DB
