Non-Contending Teams Should Be Trading Their Good Relievers
John Rieger-USA TODAY Sports  Most relievers are volatile and
only valuable for a small window of time. Therefore, they aren't
franchise building blocks. When a team isn't in contention, why
aren't they trading their more dominant bullpen arms for
prospects? Kansas City made this mistake before and they
shouldn't repeat it by holding onto Greg Holland.  Relievers are
volatile, especially after they turn 30 as proven by Bill Petti.
So Dave Cameron thinks that teams with young, dominant relievers
who rack up saves, such as the Minnesota Twins and New York Mets
should trade them while they're still effective and valuable.
The Royals haven't fielded a great, competitive team in over a
decade but they had a lights-out closer to save games for them
whenever they were able to win in Joakim Soria from 2007 until
2010. Signed to a team friendly contract and bolstering a
strikeout rate over 25% for four years straight, the Royals had
plenty of opportunities
