On the Volokh Conspiracy, David Bernstein said:
Rand ... indirectly persuaded me that caring about the success of strangers on sports teams that happen to carry the name of my city or school is a waste of time. This freed up thousands of hours for other endeavors more directly related to my own life. (I’m not an evangelist about this; if you enjoy rooting for sports teams, and think the opportunity costs are worth the enjoyment you get out of it, more power to you.)
I asked him what passage(s) convinced him of this. I thought I had heard of or read such a Randian passage that dealt with the topic, but some say Rand never wrote such a thing. He replied:
I'm pretty sure that Rand actually wrote somewhere that one can properly enjoy sports to watch athletic greatness, but that rooting for a particular team is irrational. But it wasn't a particular passage that did it, it's the overall idea that one should aspire to one's own greatness (or as great as one can be), and not be a "second-hander."
Can you help me get more specific? Where might I find some relevant passages?
