Exactly. With the loss of Digi that leaves an already very weak linebacking corps even weaker. If Poz goes down, for instance, we will be stuck with either Pat Thomas or Marcus Buggs as our starting MLB. While Wilhelm may not be a dynamo, he at least is a veteran who has starting experience with one of the NFL's elite teams over the course of the last 5 years. You really can't tell me that he would be any worse of an option backing up Poz than what we already have.
Of course, I assumed that we would have signed a veteran OLB to start over Ellison months ago, and we all know how that has turned out.
