I've had Tom Compton on the Vikings since Thursday when he first signed and Patrick Scales is an ERFA with the Bears (not tendered though so I released him). He's never been with the Raiders though and wasn't recently signed, you've got him confused with Andrew DePaola who signed with the Raiders back on March 15th.
I don't have a roster without the rookies sorry.
I switched Aaron Lynch to ROLB (he was a RE in SF's 4-3 defense last season thanks for the heads up because I forgot the switch).
