After a quick look this is what I came up with. Not sure of practice squads. Everything is pretty fluid, but I think most if not all of these guys stick. For awhile at least. 9 players, pretty good. I wonder if anyone else in USA has more?
Trent Taylor, 49'ers
Vernon Butler, Bills
Jeff Driskel, Broncos
L'Jarius Sneed, Chiefs
Xavier Woods, Cowboys
Boston Scott, Eagles
Amik Robertson, Raiders
Jaylon Ferguson, Ravens
Justin Ellis, Ravens
