Who might replace Wickman?

I think that Wicky still has the mental toughness and bulldog to close, but, unfortunately, the body is not as willing as it used to be. Sure, his velocity is good, but that isn't what it takes to get people out. His stuff used to be nastier. It's the combo of velocity and movement. The only other member of our staff who is mentally tough enough and has proved it is Howry. We probably should make that commitment now to lock him up as our future closer. We do not want to relive 2004, where our bullpen floundered for lack of a reliable closer. And how far over the hill do we want Wicky to get before we give up on him?
