Creaky Wood?

Will Carroll does his Cubs "Team Health Report" today on Baseball Prospectus (premium access only). In the report he gives grades of Green, Yellow, and Red for player health. I found this part of the report interesting:

Red light - Kerry Wood: I hate myself for writing this, but Wood shows as a major injury risk. The vague diagnosis on his triceps problem, his workload, and his relative youth all work against him.

But then, you read this:

Yellow light - Ryan Dempster: Tommy John surgery is an operation with a 90% success rate, according to Dr. Jim Andrews and other leading orthopods. ... There's a five-year "honeymoon" period after TJ where the arm is nearly indestructible outside of two exceptions. ... shoulder and nerve problems...

That triceps injury that DL’ed wood last year was two months long in healing. And, as Will notes, the Cubs were very vague about it. Let’s do some rampant speculation here. It wasn’t the triceps, it was a nerve injury. Wood had his TJ surgery in 1999.

When did that five year "indestructible" window end?

How confident are you in Kerry Wood to last all of 2005 now?
