Baseball begins in the spring, when everything is being reborn. Football begins in the fall, when everything is dying. In football you wear a helmet. In baseball you wear a cap. Football is concerned with downs.
Baseball is concerned with ups.
In football you receive a penalty. In baseball you make an error. Football has hitting, clipping, spearing, piling, personal fouls, late hitting, and unnecessary roughness. Baseball has the sacrifice. Baseball has the seventh-inning stretch.
