Joel Sherman notes that the Mets are benefitting from the number of closers available on the free agent market:

Now the Mets do not like Hoffman's stuff, and if you were guessing where Wood would end up, then playing for fellow fireballing Texan Nolan Ryan's Rangers would be a good bet (he is the team president). But the definitive league-wide availability of Hoffman and Wood only further saturated the closer market. And only gave greater confidence to the Mets that they not only will find a closer this offseason, but find him via free agency, which is their preference because that would allow them to protect their farm system.

The market has become so saturated, in fact, that an AL official regularly in touch with the Mets executives said it was his perception the Mets will wait to see if supply-and-demand take holds and the price falls, especially for the two main free-agent closers, Brian Fuentes and Francisco Rodriguez. As Hardball previously has reported, the Mets' main targets this offseason are Fuentes and Derek Lowe.

Having options helps prevent teams from being held up by players.
