The book Moneyball,
by Michael Lewis, revived some of my interest in baseball as a
contrarian numbers guy. For a friend of mine, it was rotisserie
baseball (it requires daily adjustments, so I stick with fantasy
football). I agree with Paul that Joe Morgan’s Sunday Night Baseball
commentary is some of the best around to think about the game. The
history of the game could also provide some appeal.  More than
most sports, baseball is about storytelling.  Football lends
itself more to moments–improbable touchdowns with no time left, etc.
Even those big moments in baseball, such as the homeruns by Bucky Dent
or Kirk Gibson demand some backstory. The final out of a perfect game
looks like any other out. Of course, a JLF trip to a Bulls game may be the perfect learning/teaching experience.
