The interpretation aspect will almost always come into play in whatever circumstances occur.
eg if Priestman is a red because of clear goal scoring opportunity the why not award goal and not send player off. Would almost certainly discourage deliberate fouls as potential for striker to miss/goalie to save is higher.
but what about Gordon situation. He definitely deliberately brought player down but surely he, along with pretty much all except Var official, thought it was a yellow and nowhere near being a clear goal scoring opportunity. Rule would then be faced with specifying how far out, how many players closer to goal, whether a shaved beard increased SoDs aerodynamic interception sprint speed etc.
Sin bins to remove absolutes in a game might be closest to trying to avoid ruining spectacle. May even make the 10/15 mins more exciting as team with advantage try and press it.
id be quite happy if Gogic and few StM bruisers were shown early reds right enough.
