Makes me think that Scotland is a breeding ground where managers learn their trade before moving in. Butcher moved on too fast and in to clubs far too big for him. Contrast with, say, Paul Lambert who was a bit of a failure at Livvy. He learned and then moved on.
Then again, some managers just suit some levels. When JJ was with us I thought he could go on to another club and win titles; but no, Falkirk were just about his level. Yogi, too - though I still think he could do a good job somewhere.
