Warrior General Games

so I'm starting a 3-4 front seven, but I have one question... although no one may know this answer. This question is regarding Defense General. Do both ILB's need it... or merely one of them?

I'm doing 2 experimental ILB builds so their build progress will be different and they won't be utilizing their SA's for a while as they're slow builds... but I'm just trying to figure it out for the future.

Any insight would be great.

it picks randomly between the two, every play, as far as I know.

ok so essentially you have to build the middle two, SA wise almost exactly the same.
