One of the many games I watched this past week prompted this question; it might have been Arsenal's Friday match with Newcastle. Anyway, the CR talked over and over again to the players, only cautioning once. The thing is, it didn't really work, and in the end he had to pull out the plastic a few times, and the players, by their demeanor and body language, didn't respect him. My question is, is there a ratio a CR shouldn't go past in a match? Or is the right "unit of measurment" not the match, but each player? (By that I mean, should a CR not pay attention to how often he talks to players, but only to how often he talks to each individual player.) Thoughts?
