I am careful to use the word re-tool here instead of rebuild. Nobody wants to see a prolonged losing stretch like that of the Marlins come to the St. Louis Cardinals. Instead, I would like to take advantage of the current trade market while also keeping the team in a place to compete again as soon as next season.
The Yankees did a great job of doing this in the past, and now they find themselves built for the long haul. It is going to take a lot of roster churn, but should the Cardinals give up on 2019, there are a lot of options to turn current players into a talent for down the road.
