Look at what happened to Paul Butler, here is a guy who played hundreds of league games at the top level and he had a stinker of a debut, I think Stan would prefer to ease McCarthy in against weaker opposition than the dutch. I think Butler needs to be given another chance, not sure if he is still interested though.
As for Doherty, what he lacks is composure when playing CB, unless he has improved dramatically since his Spurs days? I haven't seen him play very much for Norwich.
Damien Delaney and Graham Coughlan are the only other options I am aware of besides McShane and McCarthy.
I would prefer to see Harte ( I'm not a big fan :D ) play ahead of most of the above named, depite his lack of pace he has experience and would't lose his head. I think Stan is looking for steadiness at the back.
