Relief pitching?

If the Rockies are unwilling or unable to sign a significant free agent pitcher or acquire one via trade what are your thoughts on them using the cash that they have freed up from trading Holliday (and will hopefully free up from trading Atkins) to sign a couple of GOOD relief arms?

Cruz is the guy who I am thinking of specifically.  Beimel and Cruz would both take more years and more money than seems prudent but over the last 5 or so years EVERY signficant free agent reliever contract has looked silly at the time that it was given out.  While giving muli-year deals to relief pitchers is not the best value in baseball nor the most risk averse option in baseball it IS a pretty predictable and relatively inexpensive method of improving a team.

The Colorado bullpen is going to get a LOT of work in 2009
 and giving someone like Cruz a 3 or 4 year deal that might suck in the final year provides the Rockies with a lot more flexibility than trying to sign a starting pitcher for 5 or 6 years or a position player for 6-8 years.  Both the total annual salary and the total value of the contracts are smaller for relief pitchers.
