The Cubs-Cardinals rivalry has already started to heat up and we're not even into January yet.
When Jason Heyward was introduced by the Cubs last week, he explained his reasoning for coming to Chicago as wanting to be a part of — and grow with — the Cubs' young core. He said in St. Louis, the Cardinals' core was aging and soon, he was worried he'd be the only one left.
Heyward specifically pointed to the ages of Yadier Molina, Matt Holliday and Adam Wainwright, not to call them out, just simply to explain that they're not going to be around forever.
