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: IWll is so passionate when he talks about baseball .
