One increases team speed significantly at the position. The other has solid pass rush capability. So for me that gives the team a better chance at splash plays while being solid run defenders. Jack had injury/production concerns when he came aboard it was a risk but a possible high reward. These two have less of those concerns as there wasn't drop offs in production.This feels a lot like trading one set of mediocre players for another set of slightly younger and cheaper mediocre players at ILB. Here's hoping a serious investment of capital is to come.
The point on scheme is big tho, our ILBs are constantly getting abused in coverage by opposing offenses but I never see our offense doing it. Obviously Canaduh blows, but I don't watch a lot of NFL other than the Steelers...do other teams have ILBs that can cover? Or do most teams not ask their ILBs to cover?
Better to try and fail that not try at all.
