That's it. He's not good enough defensively to play CF full time and doesn't hit with enough power to play one of the corner spots. From what I've seen in both the minors and with the Cubs his arm his strong and accurate and he's a decent route runner, but nothing spectacular. I'm not sure why so many people here are so down on him, I think he might be able to start on a team that gets power else where, but for most teams in the post steroid era he's likely to be a backup. Personally, I'm not "down" on him altogether. A 4th OF can be very useful. I'm just down on the idea of him as a starter with the way this OF is constructed for now and likely will be for a while to come. If the Cubs had sure things who were younger in one or both of the other OF spots, OK, but that's not the case. As it stands right now, looking to make Colvin a starting position player wouldn't be likely to help this team except in regards to payroll. It's not only that lack of other OF, but the other corner infielders, and no "Chase Utley" type to provide replacement power at another position. Yes, exactly.
