The group was exposed in a few games last year

Remember the Jets debacle- blow coverage for easy touchdown, allowing 60 year old Frank Gore to drain the clock on them with a run and a simple outlet pass in the flat.

And let's not even talk about the Packers game where the whole defense - including the ILB's looked inept with Donald being injured / out. You can only ride 2 playmakers (Ramsey and Donald) for so long until someone else needs to step up.
