What did the Cardinals do that makes them look like they care? Out hit the opponent? Out pitch the opponent? Run the bases well? Play good baseball?
What does a baseball team look like that "cares?" Is it the dugout ritual handshakes? Maybe the after hit symbol flashing to the dugout? Arguing with the umpires? Plunk a few batters to start some rumbles?
Plain and simple, one team is playing good ball, the other is struggling. So, one looks sharp, the other looks bad. All these deep, mystical reasons are fun to ponder, in an angels dancing on the head of a needle kind of way. Go pitch, hit, field, and run the bases, I'll bet they look like they care, regardless of their personalities.
