I hear we need an ELITE DE. It makes me ask.......

If AD is almost ALWAYS double and even triple teamed, must it take a ELITE guy to step up? It baffles me that AD can occupy so many on the O line but none of the other three seem to exist. But yeah......Imagine having Wistrom and KC at the ends with AD charging up the middle????? WHOA! And a London Fletcher at MLB ?????? DOUBLE WHOOOA!!!
