Closers certainly have more value, but teams will give good value to elite setup men as well. Plus, this is baseball, once you've done something you are considered that type of player (hit .300, drive in 100, be a GM, manage, be a closer). Both of these guys have histories of racking up save totals, a lack of save totals from April thru July isn't going to suddenly cause teams to doubt if they can handle the role they've already handled. And yes, teams are still trading a lot for set-up men.
