It's not just missing joy to me, but your point is well taken.
I'm not discounting the loss of Papi as a major factor in the lessening signs of joy.
I just don't seem to see (or feel, I guess) that this team has a strong will to win. Grit. Determination. Whatever you want to call it. It's just a gut feeling I've felt watching these guys all year. That being said, I've never thought watching guys break their bats or throw things in the dugout in disgust after making is the type of positive energy that contributes to a team's well-being. To me, that is not the "fire and desire" I like to see. I'm talking more about the dugout seeming more alive and caring about what's going on in the game. They seem distracted or uninterested. I could be wrong about my perception. I understand that. Trying to read body language, thoughts and feelings from a TV set has severe limitations. I've only seen 7 games live.
I hope I'm wrong, and I'm not really sure that even if I'm right, "fire and desire" is really important, if the the skill is there.
Maybe a few big wins when crunch time really comes can instill some fire. Maybe the desire is already there, and I just can't see it. Maybe desire can be acquired in a short time. I'll settle for a ring from a bunch of drones over a lot of excitement and being swept in a playoff series again.
