I use "8 In The Box" a lot. Its a 4-3/Cover 1 [Run Stack] where the MLB and SS Blitz. I use this in a lot of 2-wide sets, shifting and blitzing from different spots. Its a highly versatile D scheme. Note: Sometimes I do not blitz anyone and simply call it "Spy In The Box."
Before you install this as your base scheme, though, know that I research the other team and really only employ it against running teams. Throwing 8 in the box begs the other team to throw. If they do, its usually "good night, Irene."
In order to adapt this to a team that throws to the TE, simply blitz the MLB only and let the SS double-cover the TE [LOLB is default coverage]. You will now rush 5 and allow your Linemen to be 1-on-1 [MLB occupying the RG]. The WR's will be 1-on-1 with your CB's and the TE is wrapped-up with the LOLB/SS. If the RB goes out, the ROLB will cover him, else fall into coverage on WR1.
As I said, if your CB's are suspect, you get crushed if the QB has time to throw.
