stew should be fine. this is the first training camp and preseason in recent memory where he's been a full participant without that nagging toe injury that always seems to be a problem.
smith i'm not worried about either.
beason at 85% does worry me. the linebacking situation, however, does not, with keuchly playing like a terror and jason phillips able to fill in solidly in a backup role. beason needs to be brought back when he's good and ready and not a moment sooner.
Honestly I'd like to see Beason be in a role similar to TD's. Used sparingly and be brought along slowly. No reason to rush him back off of a major Injury. The issues he has now are probably related to imbalance with the heel, ham, quad etc.
