Black didn't regress at Rangers though. He was rubbish from the first kick (I suspect it was a man rather than the ball) and apart from a period of 3 months or so in 2013 he maintained a level of rubbishness. You can blame the manager for a lot of things but a player of Black's age and experience doesn't need his hand held to be able to get the simple things right in a game of football. His failings were all his own.
