People can only base their opinions on what they have seen and if Busby, for example, performed well on that day then that is the basis for their view.
Unfortunately we do not get to see the FL guys that often, unless we support a team in Lgue 1 or 2 so dont have a wealth of "insider" knowledge
Football is political, hopefully less so in this country, so appointments will always have some form of bias
On a separate note pleasing to see a number of first year referees involved in the play offs (before SG2 they would have had a few Championship games by now)
