Neither you nor I have a clue as to what coaching Beni is or is not getting. All we know is he's been up a little more than a year and continues to make the same mistakes over and over again. Whether it's lack of coaching, unwillingness to learn or inability to learn is the question. Could be any combination of the three. If we know nothing else about Farrell, it's that he doesn't say anything bad about his players in public.
Tell me how coaching would have prevented the play at second last night? You can preach theory on that one all day and night, but that's a situation that you have to experience to learn from. In this sense, Farrell is right, the game has to teach you. It was a dumb play and despite that, he still was a questionable replay reversal away from pulling it off. That smacks of a guy who's been able to outrun mistakes since he started playing. The only thing coaching would have done there is coach aggressiveness out of him, and we don't want that either.
