I think Charlie Slater fancies moving on to bigger and better things in sports/football commentary and Notts County was supposed to be his first major step in that direction. He's probably figured he won't attract much headhunting attention if he's not even technically on the airwaves anymore, relegated to the broadcasting hinterland that is doing online commentaries to a few hundred listeners, so I wouldn't be surprised if this isn't either the start of a gradual move away from being lead Notts commentator, or perhaps even the end of the line.
