This debate would be a lot more straightforward if Bush's last 4 red hot starts hadn't been ... at home. You say "he's red hot", I say "Of course, he's at home!" I don't see a great logical disconnect with the premise that Bush just really likes the mound in Milwaukee, or whatever it is. In fact, that seems far more plausible than saying that he just does particularly bad at Park A, but not Park B. At any rate, it's far from a sure thing that if Bush were pitching every game he'd somehow do well in all of them, so I don't see where the difference over the remainder of the season will be that great anyway. If McClung carries a 6.00 ERA, then yeah, Bush probably would've done better. But I think the odds are with both of them doing about the same. If the premise is correct and Bush wouldn't have done well on the road, then hey, we picked up a couple games. The biggest question mark is how it will affect the bullpen.
