I am trying to understand the logic behind the relief pitcher spot on my roster. I currently have 2 closers (Nathan & League), but I've heard that using starters who qualify as relievers is a better strategy. Is this the case? If so, should I attempt to scoop up guys like Luebke & Samardzija off waivers?
My current pitchers are:
Halladay, Billingsly, Kennedy, Bumgardner, Worley, Zimmerman, Duffy, Nathan, and League.
