Innings are the most important stat. Nothing hurts a team more than having Koronkas pitch for them. In '04 the Cubs had Rusch and Mitre pitch when Wood and Prior were hurt. BP isn't loading for some reason, but I'm going to venture they had a positive VORP since they combined for a 4.44 ERA and a 1.33 WHIP as starters. '05 is harder to figure because there's a rotation spot open even if both were healthy. Dempster, Williams, Rusch, Mitre, Hill, Koronka, and Leicester all started games, combining for a 4.97 ERA and a 1.47 WHIP. Not that great, but probably not below Replacement Level. Well, you ask yourself which pitchers would occupy that spot if they both were healthy. Hill and Koronka played only because of those injuries, no question. I think Dusty said he put Dempster in the rotation because of the injuries at the start of the year, so add those. I think that leaves a few more, one or two each from Williams, Rusch and Mitre.
