The Padres got a large dose of that Tuesday when the club's most tenured player was traded away to create an opening for one of the organization's top prospects.
Farewell, Will Venable, a Padre since 2008 who was a leader in the clubhouse and the community, in addition to being a multi-talented baseball player.
Welcome, Travis Jankowski, who, if all things go right, could be the Padres center fielder and leadoff hitter of the future.
Of course, we don't know what the future brings.
