The Pirates have a better team on paper than the Reds? Really.... I'd be interested in seeing some detailed analysis about that.
As a thumbnail, the Reds seem better at first (although it's close), second, short, center, and right field. The Pirates seem to have catcher, third, and left (or whatever position Giles plays; the other two are advantage Reds). Pirates have a better rotation, Reds have the better bullpen. Bench I'd rate about even (if you're not counting the DLed Castro).
But it's all just opinion, of course. Pittsburgh definitely should be better than 2002. But so should the Reds.
