Harper has the power to fix an offense that scored one or fewer runs in 40 games last season. But he also struck out more times (169) than any Cubs hitter. A team ready to re-emphasize launch angle would love to add the reigning 2018 Home Run Derby champion. A career slash line of .279/.388/.512 for a player who has averaged 32 home runs and 91 RBIs sure looks appealing. But as seamlessly as Harper would fit into the celebrity culture at Clark and Addison, Cubs fans might want him more than their team needs him.
