Would hardly say Roos was an unknown. I know what you mean he wasn't a senior coach, but he was a champion player of 350 games at two clubs under many great coaches.
Obviously I don't know who our next Coach will be, but there is one thing I am confident about, if it is not Sheedy our record membership will drop and our perilous financial position will not improve at least in the short term. Sheedy would attract members and sponsors. The club would gain enormous PR. I know that is not the reason to appoint a Coach but he is the only (multiple) premiership coach in the group and if he failed say after two years he could be replaced and we could be in a strong financial position. If one of the others failed it could be a disaster on and off the field.
