I think it's fair to look at Mallee. It would be seen a scapegoat move but that's probably both untrue and unavoidable. I think what people have to remember though is that the Cubs sought Mallee out because his approach to hitting dovetailed with what they already believed and the metrics were telling them, so any potential replacement would be unlikely to come in with a radically different approach. They would likely have a different type of personality, maybe some different angles in teaching the approach, and I wouldn't be surprised if they would have a new approach to reading the metrics, but the basic idea of working the counts, wearing the pitcher out and using launch angles and other metrics to increase slugging are almost certain to remain.
