Very misleading and a bit of a straw man argument.
One of the four was Palpelbon, who was only “established” because he got that way inNoston.
Also this whole “not anyone can close, especially in Boston” and the unsupported statement about the strings of failed closers. Who were they again?
Why is closing different from other bullpen roles? The most critical situation in a game comes up in the 6th through eighth inning more often than it does in the ninth, which was the actual moral of the Closer by Committee (or, as it should have been called Closer by Chad Fox) experiment in 2003. I mean, a huge chunk of save opportunities are 3 run leads. Should the Sox really designate their best reliever as a guy who can “shut down” an opponent for 3outs before he gives up 3 runs? Closers need to be good pitchers, but not necessarily better than the rest of the bullpen.
It’s funny how sports fans think of closers as athletes with a special skill that needs to be maximized to keep from losing. But no one ever feels that way about kickers (who really do have a special skill).
