I agree, there isn't an obvious choice. John Coleman i think would be an unrealistic option even though stanley are struggling. Its the age old debate we've had each time we've kicked out a manager and each time under KT we have gone for an "experienced" pair of hands (not including Rob Page, who in my mind was a punt on someone who might be on an upward trajectory)
Personally, i would love Gary Rowett, before you all jump on me i know he is unrealistic but apart from Stoke, which as its now apparent are not just a manager away from success again, he did great things at the other clubs (burton, birmingham etc.) and it was basically his team which Hasselbaink inherited and left to go to QPR before he got found out.
Rowett would be fantastic, even at Stoke his record was decent and it looked like he had turned them around. As you say though, an unrealistic option.
