When Cubs business president Crane Kenney stood before a roomful of Cubs fans Saturday and described the relationship between spending and winning as a “chicken-and-egg” question, he unwittingly summed up everything potentially wrong and dangerous in the business approach to the team’s rebuilding plan.

At the very least, he summed up the message delivered by management during a 42-hour Cubs Convention devoid of buzz, optimism or straight answers: That this process might take longer than many envision — perhaps lasting until the end of the decade.

As baseball and business executives touted their big-name Class A players and bragged about their new $6 million Dominican academy and a publicly funded new spring facility, it became increasingly apparent there exists a sizable gap between available resources and baseball spending that could help assure the success of the rebuild.

“One of the things we were smart about was not to put a timetable on it,” baseball president Theo Epstein said as the convention opened Friday, acknowledging unforeseen delays in some of the business-related parts of the plan.

When asked about specifics, Epstein refused to talk about his budgets, any of the team’s other internal resources and decisions or the perceived disconnect between the business and baseball operations — except to suggest they’re on the same page.
