Summary: Double the fun! Last week, I had 15 baseball coaches share the lessons they've learned in 2017, including Justin Stone of EliteBaseball.tv, Tucker Frawley of Yale University and Billy Boyer of Seattle University. This week, I have 15 more baseball coaches share, including Paul Niggebrugge, Rick Strickland, Houston Astros hitting coach Jeff Albert, Tim Corbin and more. This is Part 2 of a two-part series.
