Last year I totally understood the decision to trade each of the big three Cubs, even if I felt sad about them leaving. I seem to feel at least as sad this year about losing Contreras and possibly Happ, but I'm less clear about the necessity of doing it. I sure as heck hope the Cubs get an awesome return for Contreras, and even more so for Happ, given his age and the potential he has for being a building piece going forward (with another year to reach an extension).
