Maybe if the Dodgers REALLY want Harang, they'll take Taveras too.
To me the outfield looks pretty cut and dried:
Bruce in right and Stubbs in center every day until the Reds are ready to cut bait on them.
Left field will be Heisey's to lose and Dickerson will get playing time resting all three starters. They're all young guys, so the more at bats they get the better...it's not about their performance, it's about their development. Ideally you don't develop your entire outfield at the same time, but the Reds will never have the ideal situation until the disparity in MLB is fixed.
Of course, if they do manage to trade Harang and Taveras's salaries away, they might actually sign a decent left fielder for a year...who knows?
