In a league with holds, the actual value to your team would be about the same, but Ryan has more perceived value such as for trades. It would depend on your individual league for how they rate setup men. Most leagues don't value them enough so paying full price for them makes no sense. In any case, take BJ Ryan. People are always willing to deal MR's for closers, but usually not the other way around.
