the thing about the 4-4 is that its symmetrical so if i need to flip it it still looks the same, thats why i like interchangable DE's and OLB's on both sides of the formation, i like an even look for my 4-4 scheme cuz that way i can bring heat from one side and not worry about coverage on the other then, flip it and still not have to worry, both my DE's drop so having guys like cole, abiamiri, fokou, and gocong that can play DE and drop as coverage guys is real nice it all really depends on your scheme and how you utilize your players though.
