Easy....
SCHEME 1
Play cover 2 any nickel formation. The LB's will clog up the middle of the field and cover a little of the outside. Your CB's will cover the rest of the drag route once the WR gets outside of the LB's.
I take my DE's and have them both spy the QB. Take control of your fastest DE and have him run the WR thats dragging. Usually this throws off the QB then he starts looking for his/her other options. If he waits to long to find an open receiver you'll most likely get a sack.
SCHEME 2
Play Nickel Cover two man
I like this one the best because you have the two safeties playing zone you can have them play inside, outside or over the top so you don't get beat deep.
You'll have 4 LB's and your two corners playing man, so every receiver will be guarded. Also look for LB's who are fast and hopefully have ok coverage skills...
with my D-Line Ill drop one of my DT's in a deep zone from the line of scrimmage so he clogs the middle. This time I put my one of my DE's in QB spy.
I put the outside blitzing LB in a QB spy also and I take control of him. I use him to double any receiver dragging.
You can also spot light a receiver that'll make your defense give extra attention to that player.
