Maybe that's exactly what they did.... and identified that there *is* a need to bring Rusch back as insurance? They charted Mitre's pitches, and noticed that he doesn't have anything that he can throw consistently in the strike zone to control the count. They watched Koronka; and made the logical conclusion that Rusch was a better bet. They watched Guzman in Arizona... and judged that his arm is iffy and he doesn't have any control at present, so they aren't sure if or when he will. They charted Wood going to surgery, and couldn't conclude that he'll be healthy and good. So they perhaps charted Williams in as #5, Hill in as #6, and Rusch in as #7. Hill may be removed because he may be invaluable in relief, or may be too wild to be good. Wood may be removed because he's injured. Prior may be removed because he's injured. Z may be removed because he's injured. Williams may pitch worse than Rusch. Seems to me there is plenty of reason, given the age and fragility of the front 5, to think that the #7 guy might be needed, and might be worth $2.5 million bucks. To want some insurance other than Koronka and Guzman as your #7 starter, I guess I don't see why that's so crazy. If Wood, Zambrano and Prior are hurt, or perhaps or, it doesn't matter who our 7th starter is. Might as well go with youth.
