Aaron Beasley is a guy that could be a safety or add 15 lbs and he's a linebacker. I imagine he will see the field more as the season goes on. The starting lineups for both offense and defense are going to look different as the season goes on.
Stopping the run is going to be the biggest question mark next year on defense. Pass rush should be pretty good.
Solomon is another, hopefully gets cleared, and can help solidify the DL, would certainly help the run defense concerns.
