i would not waste any assets (especially guys like cash, castro, the jacksons, etc) on any starting pitcher right now... and especially not on a rental of an older pitcher. we're looking set with starting pitching for at least next year. zambrano, dempster, wells, silva, cashner, gorz, marshall, jay jackson, etc. some of those guys are obviously suspect and could suck, but i think it's a pretty safe bet that we'll be able to put together a solid rotation out of those guys next season
