That's probably as good a definition of a successful manager as you're likely to get.
Mr Millerman, there are a lot of Scott-haters on this website and you need to read what you see here with a good dose of salt. Judge Scott on his record. An L2 championship medal in his first full season with Brentford. A decent enough season-and-a-half in L2 and then a catastrophic January, followed by the axe.
Like the vast majority of managers Scott has his good and his bad qualities (sometimes the same thing, differing only according to the context). It's true that his man-management and his public relations skills are a work in progress. However I think you would be well advised to let him get on with his job until it's clearly established that's he's not up to it, and as far as I can see, with Rotherham just four points off a play-off place with almost half the season still to go, it's far too soon to be thinking about P45s.
There are some loose similarities between Scott's situation now and that of Uwe Rösler here at Brentford (though I think Rösler is the better manager of the two). They are similarly placed in the league in their first season with their current club. In both cases, the team have gone off the boil somewhat following a bright start, and the natives are getting restless. We live in an age of instant gratification and too many fans appear to think they have a right to success here and now, on demand. Football, as you're probably wise enough to know, doesn't work like that. Managers, like players, even good ones, are fallible and have their good and bad periods. They have their ups and downs, they work by trial and error, and they need time to grow into the job. When everything clicks and everyone is on song, it's terrific and we have the best team in the whole goddam league. When it doesn't and they're not, the same players are a load of donkeys and the manager doesn't know his Rs from a hole in the ground. Give him another 10 games at least. Better still, give him another 12 months.
