For those who haven't seen it yet, this is actually a really nice story about the "culture" of the Kansas City Royals among players leftover from their glory days. The "moment" is more captivating than the marketing hype that touts a team of celebrity millionaire owners . . .

Here's the best write-up documenting the gesture:
Players can be superstitious about their uniform number. Some players succeeded early on with their number and want to keep that mojo going. Others may have chosen their number to honor a friend or family member. When players change teams, they may want to retain their number, which means a new teammate may have to give up their number.
