The conventional wisdom in baseball circles is that an MLB team never, ever invests in a spring-training facility. Sure, you may have the Pittsburgh Pirates invest $2 million in Pirate City, while the Cincinnati Reds talked about putting $10 million in an Ed Smith Stadium rehab. But those offers don't happen very often; the template is a municipality picking up all the costs of a spring-training complex.
The Chicago Cubs, however, may be on the verge of turning that conventional wisdom on its ear.
