There's an interview from Tony Gibson on Rivals:
On Mike Jones: "Mike is a big safety that we'll probably end up moving down [to linebacker].
On Isaiah Bell: "He's a physical kid, big enough that he could move down to linebacker if need be."
Obviously, the season isn't here yet, and anything could happen. But as I've said all along, I expect that Jones will be an OLB and Bell will stay at safety. In my opinion, Bell's ball skills are too good to put him at linebacker. But whether it's at linebacker or safety, I'm looking forward to seeing Bell on the field. I think he's going to be a good one.
