Chuck Garfien, Ryan McGuffey and Chris Kamka break down the White Sox signing of Welington Castillo. What does it mean for the pitching staff? How does it affect top catching prospect Zack Collins? Plus, Garfien explains why Castillo will make the White Sox more competitive in 2018. They all give "the one thing" the White Sox need to do at the MLB Winter Meetings next week, how they would have pitched Shohei Otani to come to the White Sox and Chris Kamka gives a heartfelt plea to get Minnie Minoso in the Hall of Fame in the debut of Kamka's Corner.
