It's not the same. in the 3-4, the ILB is only responsible for half the field. In the 4-3, the MLB is responsible from sideline to sideline. How is that the same?

Irregardless, you only need the mike for about 30% of the plays. Most of the time the defense is in the nickel and you would only have Lee and Smith on the field.
