I voted "I'd like to see him do better but..." there's no a decent alternative right now. I really doubt Saunders -the best option available IMO- wants to come here right now. Eddie Jordan? Maybe at the end of the season, but right now it's too early after his experience with the Wizards. And I prefer give another oportunity to Musselman than see Avery Johnson or Sam Mitchell coaching the Kings 
.
I think the best option is end this season with Theus and see what happens. If it's horrible, then fire him inmediately at the end of the season (same as Musselman).
