I just tried to explain that to you. He is driving the mentality of the team, making sure the entire team is on the same page.
You seem to just say well if he wasn't here, we would be fine. But nothing to support that except well Pettine is a good coach. No one is disagreeing with that but I see a whole different attitude from the TEAM that I haven't seen in a long time. The HC sets the tone of the team. So I credit Marrone for that
