Joe Maddon the very impressive manager of the future World Series Champion Tampa Bay Rays (hopefully this year) has had only 3 meetings this year with players. He is known as the easiest going manager in baseball with few rules and very little temper. When younger, he would have countless meetings until he realized no one listened. So, he decided to have Team Meetings only when needed, which is 3... in a year.
His first was before Spring training got going (February 20). His second was after losing 7 in a row (and in the outfield- and not yelling). His last meeting was after a road victory as the Rays were up by 1 in late July. He lit into the team for lack of effort and tore them a new one.
Then... no more meetings. Impressive to me.
Here is the story on the (hopefully) Manager of the Year.
