Who cares who they have? This isn't basketball where one or two players is all you need. They had better pass D numbers than we did but comparable run D numbers, and allowed more points.
Also, even with Addai (who had fewer yards per carry than Maroney, who gets crucified here), their rushing attack was third from the BOTTOM in ypc. 3.5 average, more than half a yard less than our "poor" running attack.
Addai is terrible.
The two most important things in the NFL today are these:
Being able to pass effectively.
Being able to stop the pass.
Being able to run/stop the run are WAY down the list. Its a passing league now, whether you like it or not.
