My best set up for the Raiders is...
RDE- Wimbley
DT- Seymour
DT- Kelly
LDE- Scott
OLB- Howard
MLB- McClain
OLB- Groves
the secondary is fine stock.
However, as mentioned in a different post, this is your best base set up, but when you are in running situations, it works best to formation sub, put Henderson in at DT for Seymour, put Seymour in at DE for Wimbley and then put Wimbley in at OLB for Groves.
