Idowu is a good story but a subpar starter for a P5 team LB, a worse deficiency by far than Zeise. As is Briggs as a S.
It's frustrating. But the coaches have their sword in the rock opinion on these guys, they've thought this way 3 years now on these guys, and regardless how bad and obvious it looks on the field, they're sticking with em (meanwhile, shifting CB randomly in and out of games like ice cream sprinkles).
It's crazy, and the annual shaky defenses prove it. But as others say, it ultimately reflects on Narduzzi, no matter how many DC he runs off. And if he doesn't care ... what can anyone else do. "Have faith" I guess...
