Trade Byrd. If Sizemore gets hurt, use Colvin as the 4th OF/backup. Not ideal, but... 1) Byrd is in the last year of a contract 2) Byrd is very affordable 3) Byrd provides solid production that someone would most definitely be interested in 4) Because of these 3 things Byrd should be able to net us a fairly decent prospect in return, I would imagine. I like having Byrd on the team, but he's not a game changer. Healthy Grady Sizemore is a game changer. Going with an OF of Soriano, Jackson, Colvin if Sizemore is hurt wouldn't be the worst thing in the world, especially not in a year where the Cubs aren't 100% expected to contend for a world series title, plus it would guarantee playing time for Jackson and Colvin. I'm not a fan of Colvin as a starter but giving him extra AB's in a situation that would mean the rest of the season is a throw away wouldn't be a bad thing. Plus after next year there's a lot of good OF bats on the free agent market, including Kemp, B.J. Upton, Hamilton, Bourn, Cabrera, etc. so if Sizemore fails or flourishes, there are options at both avenues
