Typically I'll start all 4 closers at the beginning of the week until I sew up SV, then switch in my holds guys. If the team I'm facing has only one or two closers, I lean more heavily towards the holds guys early. Ideally I would roster 8 SP, but I'm making due with 7 for now. Last I checked I'm still among the league leaders in Ks and W, so it doesn't seem to be a problem. I'm also dominating saves, last I checked.
