Murton's VORP, per PECOTA: 2007: 21.5 2008: 17.3 2009: 16.3 2010: 15.2 2011: 13.4 Milledge, same: 2007: 28.4 2008: 28.3 2009: 31.7 2010: 34.8 2011: 30.5 Probably a big part of the difference is due to the fact that Milledge is projected as a CF, and Murton as a LF. In any case, Milledge would give good insurance in case Pie doesn't pan out. But, he's younger and more projectable than Murton, and has a bigger upside. He's also more likely to develop 20-25 HR power, and is a better defender and is faster. Given that the Mets have the ancient Moises Alou and Shawn Green in the corner outfield, they'd probably be reluctant to give him up, though they're certainly a team that's good enough to win it all this year.
