They aren't free agents after next season. They are most likely eligible for arbitration, but those players are under the Indians control for 3 or 4 more years each. To answer your question though, yes, I think the Indians will sign Sizemore and Peralta to long term deals like they did with Pronk and VMart. Coco, I don't know, kind of on the fence here. With the young talent in the minors, I could see them getting through this year and then trading him next offseason to fill holes via trade. In 2007 you can expect Snyder and Gutierrez to be up I would think, barring any huge setbacks.
Coco-We shall see
