Premise: Instead of indulging in the usual teary nostalgia about baseball (that means you, Ken Burns), Will considered it as a craft, explaining exactly why a manager calls a hit-and-run now and not on the next pitch, how a pitcher sets up his fastball, why a shortstop moves in a step for one kind of double play and out a step for another.

Hypothesis: Will is such an expert in explaining the details of baseball.
