well i guess I see your logic then. Beltran's trump card is definitely the stolen bases. I do not agree with your logic that you can survive this mild downgrade. I mean...Beltran is a better hitter than all those guys anyway. Chipper has the advantage of the braves lineup, but its still a toss up between the two I think. If you're set that you can take a downgrade in the outfield though, why would trade an outfielder for an outfielder? Thats more like a donation than a trade. If you want to downgrade the outfield, score an infielder or a pitcher along with a lower outfielder. I think you ahve the right idea with th beltran/penny for chipper/mussina deal, though that is not likely to go down...its the right idea though, i like that one.
Rest in peace Mitch Hedberg. I name my fantasy team "Buoyancy of Citrus", in your honor.
