I think it will depend on how he looks in Spring.
Two things to keep in mind:
1. His knee apparently is not fully healed. This has been a problem for over a year now. After missing most of 04, there are questions still as to whether he will be 100% to start the season.
2. Even if he is healthy, he may get traded. There have been rumors since 03 that the Rockies want to move him. No idea where he will end up.
At this point, I probably wouldn't touch him unless he is a reserve.
