I'm doubting it's going to happen, but I wouldn't mind seeing a 4-2 with this DL.
Neal, Raji, Daniels and Datone Jones
Of course the Packers would run it out of their 2-4 (which is the same thing as a 4-2, other than Neal and Jones don't have their hand in the dirt, which they both have done before).
With maybe Jolly or Wilson rotating in and out for Raji and Daniels.
With the rookie OLB rotating in and out for Neal and Jones.
