Steinolf has leadership experience, if you can call holding the leash of Skyclaws, basically Bloodclaws given jetpacks and told to have fun, leading people into battle.  He'd likely be fine with whoever gets chosen, but since he's not going to volunteer, he won't make any suggestions, either.  Wouldn't feel right to him to shove someone into a position he wasn't willing to do himself.  He'd even be the first to admit he's not much of a leader, having felt more comfortable leading his pack of wolves than anyone else.
