I don't understand why some of you are so skeptical about this. Sure, it's ok to be cautious but the move makes all the sense in the world for several reasons:
1. The development of Nick Perry and Mike Neal. Perry is not a bust. He's not Clay but he is doing well enough. We have a glut at OLB and moving Clay to the inside is smart.
2. Clay instantly improves our run defense and he can play a roamer in certain defense schemes, which actually better utilizes his talents rather than limits him.
3. Given the woeful state of our ILB core, this is most definitely an improvement to the weakest area of our defense without sacrificing anything. You are only so good as your weakest link, as they say, and our OLB talent is sufficient.
