Invite him to camp if there's nothing on the table for him. Other then that, I wouldn't guarantee him a damn thing. Before the Raiders came calling with HUGE money, Javon was thinking retirement. Maybe he'll consider it again.
As for Owens, I've been pretty indifferent to bringing him in. If he doesn't cost a lot, whatever. The guy can still contribute and you know Cutler ain't gonna put up with his bullshit.
