<<<<The staff's hands are tied in part because of a ridiculous policy of the Pirates. The organization forces its minor leaguers to show up way, way too early for pregame drills, often times with players on the field shortly after 1 p.m. That leads to burnout and tired players by the time the game starts.>>>>
If you're looking for me to blast the Pirates for doing this with minor leaguers, I won't. I've advocated turning the minor leagues into some sort of baseball academy for fundamentals for years.
Now, I don't believe it is helpful to have continuing mundane drills just for the heck of drilling. I do think you have to change things up...and that's where a coaching staff has to be a bit creative. You do have to have the right coaches in place for this sort of thing. Bad messengers can generate bad attitudes.
If you have been chosen to play baseball for a living, and the team is doing its best to make you a better player, you should be grateful and enthusiastic for the opportunity.
