What is the point of using a 46 defense?

i run with the eagles and have been using the 46 cover3 and user my de all over the field and have petty good coverage. sometimes the flats are alil to open.

i was wondering if anyone that is good with the 46 could give me some good plays to run with it.

i didnt even think about changing the package. ill have to try that tonight .

4-6 is a good book. ANY book will be terrible if you only use 1 formation out of it. 4-6 normal flipped to speed package has multiple corners on the field but you can still stack the box....it's good for disguising heat.
