The only concern I have with Callahan is he really hasn't stayed healthy. From a cap resource allocation standpoint, I'm definitely placing nickel back over S though. Replacing Callahan on the open market is a possibility in that regards. Bush looks ready to adequately start at S. One article I read about Pagano said he liked using a third safety in nickle packages. I wonder if that will play into any decisions (I'd assume he's still using a 3rd CB more, but the Bears aren't super deep at S if Amos goes) CB is really the only major position Pace hasn't drafted (Hall was kinda tweenerish, but moved to S full time pretty early). Wouldn't mind seeing that change this year. Though they do have Tolliver and a handful of PS guys, I'm not sure if any of those are long term development pieces.
