After dealing Yu Darvish earlier in the winter, the Cubs don't have a very strong pitching staff. They just added Trevor Williams who will look to bounce back this year. It seems like they'll hang onto Bryant/Rizzo/Baez for now, but it will likely be a middling year for the North Siders. The White Sox, on the other hand, have a great rotation. They also just brought back Carlos Rodon on a one-year deal to compete for a bullpen or 5th starter spot.
