If Chemistry really matters, you would expect an offense that was 6th in the AL in runs scored last year and was the youngest offense in baseball to take a step forward this year. You would at least expect that they wouldn’t take a step backwards.

They didn’t take a step backwards; in the spirit of the Olympics, they took more of a triple jump. The Royals are 11th in the AL in runs scored. They’re 49-65, the exact same record they had after 114 games last year. They’re tied for the worst record in the league. And keep in mind, since Perez and Cain returned to the lineup and the Royals finally put their projected lineup on the field after the All-Star Break, they have a worse winning percentage (.400) than they did (.440) before.
